N800 reboots when browsing while playing radio
 

Hi,

My N800 locks up hard and reboots itself randomly when I am browsing the web while at the same time listening to a radio stream. Sometimes I am able to load two or three pages before it happens but eventually it will go kaboom, I already had a dozen or more reboots just tonight. It is a brand new unit with freshly flashed latest 2007 OS upgrade and no other applications installed. My Nokia 770 worked flawlessly in the exactly same setup.

I would appreciate if you can run a few tests and post results here (including the OS version). Just start AccuRadio Hitkast and browse through several of the web sites in the bookmarks for 10 something minutes while the music is playing. Tableteer pages for one seems to guarantee the crash for me.

Thanks in advance!

No problem here.. been surfing for 15 minutes..

Re: N800 reboots when browsing while playing radio
 

Thank you konfoo. Unfortunately, it is progressing so I'm almost decided on returning the box after holidays. It seems somehow connected to playing any music and simultaneously accessing the net, I now had lockups with mp3 playing in the background while surfing the web...

Re: N800 reboots when browsing while playing radio
 

Are you using virtual memory on your storage card? Try turning that off - the card may be defective. If it isn't... could be anything (bad RAM, ...).

Re: N800 reboots when browsing while playing radio
 

Tried already removing the card, and no virtual memory has been set up. Still not hundred percent sure this is a hardware problem even if it looks like. One more strange thing: sometimes connection breaks but tablet does not hang and I can reconnect. But when restarting radio playback after that, the sound volume is reset to some random (usually low) level. That is, the volume slider position does not correspond at all to the actual playback volume. The moment I touch the slider with the stylus volume is adjusted back according to the slider position. Looks more like the audio driver bug to me.

Activate swap.
Increase your cache in Opera to max (Tools/Settings/Memory Cache: 4096).

StIl does it?

Re: N800 reboots when browsing while playing radio
 

I am having the same problem. I listen to a stream from the home desktop and then try and browse the web. SHUTDOWN, immediately and reboots. I tried this many times with the same results every time. I icreased the cache. I used the 128mb card that came with it to increase the vm. I turned it off. Allto no avail. Anyone else care to try it for say 10-20 min..2...E]

Re: N800 reboots when browsing while playing radio
 

Mine (on 2.2006.51-6) seems to be solid as a rock (touches wood).

I've been surfing the web (BBC News website) on WiFi (11g, WPA/TKIP, Linksys WRT54GS running Sveasoft Talisman 1.2RC3 firmware) while listening to streaming audio (AccuRadio HitKast - only testing, not my normal choice!) *AND* also transferring a 5Mb file over bluetooth from my phone to the N800. No problems at all.

My config: 128Mb virtual memory, 1024kB Opera memory cache. 1GB RS-MMC card in internal slot, 1GB SD card in external slot.

Try rebooting your device and check dmesg for any unusual errors or corruption which may give some clues, failing that return it as it definately isn't behaving the way it should.

Re: N800 reboots when browsing while playing radio
 

It's so comforting not to feel alone anymore :) slconrad, could you please share a few details about your setup?

- N800 origin, e.g. Korea, Finland (look at the sticker under the battery), and where it was purchased?
- OS version, if it's upgraded, did you install 56-1 upgrade yourself or did it come with it?
- Brand, model and firmware version of your wireless router/AP, with what security options it is configured (WPA/WPA2, TKIP/AES)?

I even came to extremes of booting to my Windows XP partition today and trying Nokia upgrade wizard to reflash it again, but that did not help either. I am returning my N800 on Tuesday. Need to decide however, what's next. I'd love to have another try, but what are the chances the next one won't fail in the same way? Since music listening and web browsing is sort of the main intended use for the box, and I love to do it simultaneously, I'd rather go look elsewhere if N800 is inherently short in this department...

Re: N800 reboots when browsing while playing radio
 

Tried it, no go. Locking and rebooting under heavy load all the time. It even rebooted a couple of times today while just browsing, with no streams playing.

Re: N800 reboots when browsing while playing radio
 

I will check soon. I am trying to reset this as well. I need to run a few more tests on this.
I purchased this from Nokia and it was already flashed with the recent firmware. I am really annoyed over this, and will call Nokia to see what can be done. Hopfully I can resolve this, as i have installed mplayer and a theme from the previous model. I installed the aim chat package as well as listed from the ok to install - on the 800 series. More later.

Re: N800 reboots when browsing while playing radio
 

If reflashing the OS doesnot help, then return/exchange the N800.

Re: N800 reboots when browsing while playing radio
 

Yes, I am planning on calling Nokia Tues. and letting them walk me through the 'procedure' they are required to do. I have flashed the machine and right away tried to browse the web while listening to the streaming media... 10 min. and restarts. I thought it might have been something I installed.

I have read a few threads about these products being made in Korea, is this in any way something to avoid if possible or does this even matter? I love the gadget other than this problem. The browser has crashed a few times with only it running. Maybe I just got a bad one.

Would any settings with the wireless router be responsible? I don't see how this would matter, I am just trying to think of other reasons here.

Re: N800 reboots when browsing while playing radio
 

Well, my initial thought was also that it might be some of the additional software I had installed, but as I wrote I did reflash it several times and it changed nothing. My next suspect was my Netgear RangeMax 240 router. I've read complaints on Netgear support forum about Intel Centrino wireless chipsets causing laptops to crash with this model. It is mentioned as a fixed bug in the changelog file for the latest firmware I have installed, but you never know what 'fixed' exactly means and what other chipsets may be affected. I also happen to change router's security configuration to WPA2-PSK with AES just before my N800 got delivered. RangeMax has hardware support for AES encryption and I don't know if N800 does, otherwise decrypting in software may put CPU under very heavy load. But I since than tried reverting to WPA-PSK (TKIP), which worked perfectly well with my Nokia 770, and also tried WEP but to no avail. It still locks up and reboots. I wish it's not a common flaw since I love N800 and would like mine exchanged or repaired. So far, looks like only two units affected, it would be interesting to compare serial numbers...

Re: N800 reboots when browsing while playing radio
 

UPDATE: I am using another wireless connection (D-Link 525) WPA security, open SSID. - All works so far...

Spoke to soon. 25minutes and 2 tries later, same shutdown occurs. I am going to send this back and get a replacement.

Re: N800 reboots when browsing while playing radio
 

It is somehow related to the connection speed. Reboots only happen when connection is really fast, e.g. full 54Mbit mode 800.11g. You'd probably never get anything even close to that with your cellphone unless you are on some 3G network, even then I doubt. I've tested with WPA already and it still blows up but takes more time to occur, like 30 min initially. After that it however goes on rebooting every 5 min. Looks like a trivial CPU overheating problem to me. Thermal grease not properly applied? I of course have no idea how this OMAP chip is supposed to be cooled...

Re: N800 reboots when browsing while playing radio
 

Just noticed your latest update AFTER submitting mine. So it's the same - 25/30 min of work initially, then kaboom...

Still wondering how many units may have this fault? You did not check where yours was manufactured?

Re: N800 reboots when browsing while playing radio
 

Tried WEP (40-bit), it only took N800 10 minutes to blow. Back to WPA2 (AES) and it has already rebooted after 15 seconds of AccuRadio playback. I think I'm done with testing, sending it back.

Re: N800 reboots when browsing while playing radio
 

Made in Korea.

I ordered it the day it was out on the Nokia website. I will call ASAP.
I have also noticed that the internet radio (streaming media) will disconnect and can't find the stream again. Also will not browse a website even though it says it is connected to the wireless router.

This is absolutely frustrating, as I wanted the functionality as advertised. I guess there is a lemon in everything (Rev. A) devices, but I somehow keep thinking positive that it is Ok.

BTW- Do you know how to check the dmesg through using OS X connected to the N800?

Re: N800 reboots when browsing while playing radio
 

Exactly the same behavior here. The symptoms are somewhat connected - sometimes it will just lose connection without any indication (taskbar applet still shows it is connected), the next time it will lock up and shutdown/reboot.

I am still undecided if I should have another try with N800 or wait until I know the issue is resolved. At least next time I will try to get the one assembled in Finland just for a change :)

I guess you have to install xterm on N800 first and become root one way or another (described on maemo.org wiki). You may also install ssh, then you will be able to either open terminal on N800 and run dmesg command from there or login via ssh from your computer (you'll need a client installed on OS X too) and do the same remotely, with the added convenience of being able to use keyboard, cut and paste output to your Mac computer, etc. I am not going to spend my time on this, but will be interested to see the results if you will.

Re: N800 reboots when browsing while playing radio
 

So there are two manufacturing plants? I wonder what the odds are of getting one from Nokia. I called them and received an RMA and did want to replace it. After I described exactly what I did to replicate the problem and the procedure of flashing the drive, default configurations, etc... they just wanted to RMA it. We will see about this replacement. I wonder if anyone else has 'Korea' as the location of assembly.

I will look into this. I have (by default) shell access to the Mac (Terminal under the ulitities folder) so I should be able to proform the required setup. I will do this soon.

Check out this post

you may be running out of memory. Addd "exit 0", or move the script somewhere, and reboot. Verify metalayer-crawler is not running, see if your problem is solved?

GOOd luck!!

Re: N800 reboots when browsing while playing radio
 

Thanks for the tip. I am interested in this, as I have a replacement coming and IF the device does the same thing... I will have to see if this works. I wonder about the other users who have not had problems with browsing and using the media player. At first I thought this was due to the router, but after trying different connections and still the same results... well, I just hope it was a lemon and won't affect the new device..

Re: N800 reboots when browsing while playing radio
 

What seems to be needed is an app. to visibly monitor the memory usage.. that would quickly tell if there's a memory leak somewhere. The descriptions about reboots are consistent with the unit running out of memory.
