Public bug reported:

Today my file server and media center crashed due to an unstable graphics 
driver.
I had to shut it down hard and reboot, which in some way made my laptop also 
crash(!).
The laptop didn't respond at all, not even to Ctrl+Alt+F1. I had to hold the 
power button down like I did with the server.

My laptop had the following network connections open to the server:
- SSH session
- Two CIFS mounts, command: mount.cifs //server/share /mountpoint -o 
user=something,nosetuids,noperm,rw,iocharset=utf8
- Possibly one or more PulseAudio connections, although I wasn't playing any 
audio at the time.

This is the basic setup of the laptop:
- ThinkPad Z60m: Pentium M 2.0Ghz, 1024MB RAM, Intel chipset/audio and 
integrated ATI Radeon X600.
- Ubuntu 7.10 Server i386, multiverse repositories
- OpenBox, XFCE environment, various KDE and GNOME applications installed
- PulseAudio and Skype which are not always stable

The laptop crash occurred around 12:09

I think this is too early to have affected the crash, but I'm not sure about 
the time.
