Type "sync" at a console and then wait for it to exit.

Damn. Just fell victim to a related problem on my N800 with latest OS2008. I was copying about 150MB in 4 files from my MacBookPro onto mmc1 and went to make a cup of tea. When I came back the N800 had locked up completely and so had Finder on the Mac.

So, I pulled the USB cable and the N800 rebooted.

The mmc1 card went read-only. Opening the door and closing it again remounts the card as RW. Trying to copy files from mmc1 to mmc2 made the card RO again with an IO error. Cycling the door eventually allowed me to delete the partially written file and others that completed in the same copy operation.

The card seems to be acting normal-ish now. I've managed to do a backup to it and copy the backup folder back onto mmc2.

I don't know if anyone can shed any light on this, or if this info is of any use to anyone else, but this is the first time i've seen anything like this occur and I've used the same card under OS2007 and OS2008 beta.

I can verify there's some memory card related problems with OS2008.

I had the latest OS2007 flashed on my N800 and everything worked just fine, including both 2G memory cards.

But when yesterday flashing the latest OS2008 things changed... I was reported by OS2008 that my cards are "corrupted or not formatted" (in reality that was not the case, data on the the cards was perfectly available by other devices)

I tried several combinations with memory cards, verifying the magnet etc, even flashing the device again - but the problem did not go away.

I had no choice than flash the latest OS2007 back - everything works now.

What's the proper place to report this kind of bugs? (I visited Maemo Bugzilla but was not sure it that's the place?)

PS. The new OS2008 looks promising!

More information and at least a partial solution for my case at Maemo:
https://bugs.maemo.org/show_bug.cgi?id=2637

(even tiny differences in memory cards can cause problems, bulk cards may work or not)

I had just run into this problem on my N810.... all of a sudden my internal memory card was going read-only on me. On a fresh reboot it was rw but trying to delete files from it switched it to ro. The dmesg log was similar to the N800 posted in the bug but different. It clearly showed dissatisfaction with the FAT file system on the card.

I thought I had done the repartition and KDE installation procedure incorrectly but I searched and found this thread. The fix was the same as the N800's.... umount and redo the filesystem. NBD.

Thanks for the thread.
Frank
