Hi there,
I got some weird problem: From time to time my system freezes randomly (and completely - hard reset). This was not always the case. Unfortunately I can't remember the exact date of the beginning of this freezes (and if I could I wouldn't know what I had done before), but in my humble oppinion the problem occurs since the upgrade to linux-3.1.6. Right now I'm running 3.1.9
After shutting down my notebook (a Thinkpad L520, Sandy Bridge), often I can't even properly start it again (mostly just black screen - does nothing). In that case I usually remove the battery, wait a few seconds, put it back in and then the computer boots without problems.
Sometimes (e.g. at the time of writing this) this problem occurs more often than usual.
Until today I had no clue what caused this. I disabled a lot of functionalities in the BIOS, unplugged everything (second monitor, etc.), did a memtest86 (without errors). A few hours ago I luckily got a kernel panic message on my screen (I assume it got there "before it was too late"). See a "screenshot" of here: http://i.imgur.com/LdgFE.jpg
The "kernel BUG at fs/inode.c:427!" line got my attention - could this be a filesystem bug? I got an Intel 310 Series SSD in my notebook, running ext4 on it. Could it be possible that there is some issue with that or just an annoying bug?
Maybe someone can help
For the curious:
My fstab:
/dev/sdb1 /boot ext2 defaults 0 1
/dev/sdb2 / ext4 defaults,noatime,discard,user_xattr 0 1

Yep - did that - nothing suspicious.
