Hi, Just prior to 2.6.32 cycle I tried -next tree and noticed that after a failed s2ram (here it works only once, and I test once in a whileto see if fixed accidentally) I got a minor filesystem corruption. I am sorry I didn't report that back then. Now I have installed 2.6.32-rc2 (well -rc1...) and things were sort of ok, I have even thought that hibernation is once again stable (somewhere in the not that distinct past the hibernation which used to work, began to fail randomly on resume) Few days ago, I got a read-only filesystem again, an fsck, few more corrupted files..., It should have had rung the bell for me (I have still used hibernation, trying to understand why it fails sometimes) Yesterday, however, I have decided to fix that once and for all, and for that I have set up a loop + rtc wakealarm to make it cycle through hibernation. Needless to say I didn't run that loop more that maybe 3 cycles (and no failures), but noticed that rtc clock is dead on resume. I sort of fixed that (this is hpet emulation that strikes again), I will post when I test the fix (trivial), because when I had rebooted the system into the modified kernel, I got that readonly filesystem again, and this time the damage had spread over lots of files. (I have even lost most of dpkg database..., many programs, libraries,..., settings) Yet, thanks to Linux flexibility, after a day, and some study of nautilus source, I had the system recovered fully. (Now am doing backups.....) But I don't want that to happen again... Another clue that I have seen was that ext4 driver reported that it aborts journal replay. I know that for now there is not much you can do, but just to let you know that something is there... What is especially interesting is that there were no s2ram'disk faulure preceding the corruption, but my theory is that corruption wasn't detected for a while from last failure, probably giving such bad consequences. You do sync file-systems before entering the hibernation, don't you?
