BUG in fs/inode.c:429

[Florian Kriener]

Hello,

here is a kernel bug message of one that I somehow triggered.
I have absolutely no idea why it happend, I was reading an E-Mail
with an attached archive, that I opened and closed again and BANG.

It works now. I am however scared. This is not the first time it
happend and the others were even more scarier. So scary, I
don't even have trace of them. -- I could not find one on my
hard drive, but I have my camera ready now. BTW: The others happend
during suspend or resume from hibernate. This one did not, I am
however pretty sure, that my notebook was in hibernation before.

Here is the trace:

I am using 2.6.37-rc7 from Debian experimental and all my filesystems
are ext4 except for /boot, which is ext2 (and /tmp is tmpfs).

Please contact me if you need further info and please CC me in replies, thanks.

And thanks for all your hard work. I really love linux.

Greetings,
Flo.
