Perhaps if you had reflashed ITOS2006 they would have gone away too ?...

No it was my 2nd time reflashing to OS2006 and still the problem persist..

well i gave OS2006 a second chance so far.ok

My apologies for resurrecting this old thread - tried searching but could not find something related to ITOS2006 49-2 stability. I have a 770 since two weeks now booting from a 1G kingston mmc-mobile card (thanks to information posted by great folks here) and also have the 64MB extended virtual memory enabled on the FAT partition. I have noticed that every few days, the device would just reboot e.g. when double clicking on the rss feed applet on the desktop (home) or opening up a browser.

I installed sysklogd earlier (courtesy of a post from a gentlman here - don't remember his name) and collected some info/logs. My question is whether this is normal for 770 or should I expect it to behave better in terms of stability and if so should I try flashing it again? I have opened up a number of apps at times with no reboots observed and at times it has happened with no apparent load.

(Posting the info/logs in subsequent mail as it has gone beyond the posting size limit).

Friendly bump. (reference post #14).
So any suggestions, anyone else willing to share whether they are observing similar random reboots or that ITOS2006 49-2 is quite stable

Appreciate any feedback

I am also observing random reboots as well as white screens on the same firmware version on an N770

same problem for bluetooth scaning, it reboots when scaning. I had to reflash it.
why isn't there an explanation for this problem? what couses it?.

In general random reboots can have more reasons. Apart from corrupted flash filesystem (caused by any previous random reboot in 'wrong' moment) which can be fixed by reflash there are two main issues you can't fix easily:

1. out of memory situation - enabling swap and tuning swappiness can help with this

2. wlan driver memory corruption - known for more that 1 year but only recently traced to be definitely caused by wlan driver in 770 and still unfixed - http://bugs.maemo.org/show_bug.cgi?id=2006 This one can be behind many truly random reboots as the corrupted memory page is randomly assigned to any process.
