Package: linux-image-2.6.18-6-k7
Version: 2.6.18.dfsg.1-18etch1
Severity: normal
I've a crypted reiserfs filesystem mounted on /home, but instead of
throwing an error message, the kernel crashed.
The crash occurred when I launched Thunderbird. The panic message is
not on syslog, so I took a photo of the console and copied it.
I don't know how to get the full error message on a file, and I don't
know what information is useful. I can reproduce this bug by launching
Thunderbird with the corrupted home filesystem.
To have this trace, I launched Thunderbird from a tty. The error was
longer than the console. On the error there is this trace (note that I
didn't copy the addresses because I manually copied the screen):
Process: icedove-bin (pid: 3398, ti:c6a0e000 task:e74a9000 task.ti:
c6a0e000)
Stack: (24 addresses that I didn't copy)

<0>Kernel panic - not syncing: Fatal exception in interrupt
After, I launched Thunderbird from the desktop and switched to a tty
before it is launched. It crashed with this error:
skb_over_panic: text: ee86bdcd len:101 put:101 head:00000000
tail:00000065 end:00000000 dev:<NULL>
Note: /home is an encrypted filesystem using aes loop device.
I think the filesystem is corrupt because when I try to mount it, it
sometimes fails with this error:
linux kernel: Buffer I/O error on device loop2, logical block 32813
linux kernel: lost page write due to I/O error on loop2
linux kernel: ReiserFS: loop2: warning: journal-1226: REPLAY FAILURE,
fsck required! buffer write failed
linux kernel: ReiserFS: loop2: warning: Replay Failure, unable to mount
