i think he means its normal to be random these days

Cool!

Now it's normal to burn holes in your wallet & get reboots!

Well, the way I am using my N900, I never have any reboots. Of course one could only test the likelihood of it being a hardware issue by factory resetting (reflashing) two N900:s and then having the same person use them on alternate days and then reporting back how closely they resemble each other. The same apps, if any, should be installed on both devices.

I can just tell you that I would be absolutely furious if my N900 rebooted spontaneously on a daily basis! It would constitute an unacceptable change to present behavior for me.

At least our wanna-be creator is having a good time. :)

Electronic components all differ in their behavior within certain tolerance ranges. They are not all exactly equal. What happened is that the OMAP3 power saving support in recent Linux kernels was assuming too short a tolerance range in waking up the CPU AFAIK. Some OMAP3s wake up faster than others (a deviation of nanoseconds I suppose), all within certain tolerance levels. So the reboots are a hardware issue, but not because of broken hardware, but because of the kernel being too impatient.

Anybody correct me if I'm talking nonsense, please. :)

did have rebooting version but sent it to service week before walkaround was announced. the main reason was getbootstate-bug that "bricked" device and I had do reflash loosing all data etc. later that was also resolved and it can be repaired with flasher just by putting your device to r&d mode and back.

now i have a brand new device that doesn't reboot randomly. it is much easier than the older but i would also have managed with the rebooting one if info about those 2 bugs would have come before I lost my faith.

I hope that nokia won't include that fix in the new firmware and shorten battery life from all phones, even the working ones...

Most of the devices with random reboots have a hardware issue. It's not broken hardware, but the power saving timing tolerance thresholds of the OMAP3 CPU are too wide to handle for recent Linux kernels.

There are two devices out there with OMAP3 and recent Linux kernel, the N900 and the Droid. Both have the same reboot issues.

Now that Nokia identified the bug, they have a fix for the kernel and it will most likely be in the next FW upgrade, since this is a critical issue.
No idea, what the Droid will do, though.
If this is a hardware issue - will we have to replace our N900's? The quick-fix works great for me. Thanks for a relevant comment.

no , up to you i suppose.

i would like to think nokia would do a recall.

but one thing i know- if this bug isnt fixed in the f/w upgrade i am demanding a brand new n900.

It usually happens when the battery is low or when surfing intensely.

No. It's the way specific hardware is interacting with the linux kernel. The kernel is what needs to be fixed and increase the tolerance levels. Which, if what I read in the this thread is correct, they've done.

This mean when the FW update comes out, if they've incorporated the new kernel patch, then your reboot issues should magically disappear. No need to exchange N900's.
