Hello :)

My system just crashed because of a power fluctuation and the root
filesystem was damaged.
The system booted up just fine, but when samba tried to start up
the kernel oops'd.

xfs_repair was apparently able to repair the damage, though I seem
to have lost some files.

I do realize that a lot of awful things can happen if you just cut
the power, but the kernel shouldn't oops on a mounted file
system, right?

Please CC me, as I'm not subscribed to the lists.


Regards
Thomas
