honestly, I don't know. As you may see from the
dmesg output this box has been started on 24 april
and the crash has happened yesterday.

IMHO the crash happended because of this:
At 12:23 squid complain that there is no left space
on device, and it start to shrinking cache_dir, and
at 12:57 the kernel start logging...
This box is pretty slow (celeron) and the hda8 filesystem
is about 2786928 1k-blocks.

this box is running squid (http proxy): hda8 is where
squid cache and logs are stored.
I haven't rebooted this box since the problem happened.
If you need ssh access just email me.
This is the output from xfs_repair:
