[Bug 81557] System freeze / hang

[Ordou]

Public bug reported:

I'm experiencing complete system freeze / hang on my server (Dapper
6.06.1).

My server's is an
    * Athlon 1333 MHz
    * 768MB memory
    * Ati Radeon 9200
    * Hauppauge PVR-150
    * CNet Gbit network card
    * Two SiI 3114 SATA controllers with lots of disks:
          o /boot using ext2
          o /root using Reiserfs
          o /multimedia using XFS

No keyboard or mouse is hooked up, I use shell over ssh to admin the
box. I don't use graphical interface, so the server doesn't have X,
Gnome or KDE installed.

Since the very first day I installed Dapper I've experienced quite
regularily freeze/ hangs, of about 3 days between each one. Only a
reboot will correct the problem (temporarily).

/var/log/syslog doesn't show anything (I think), here's a snip of the
syslog around the time of my lock-up earlier:

I could really need some help and assistance in hunting this problem
down. Thanks!
