Affects: linux-source-2.6.15 (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
I didn't use the computer for a few hours. When coming back:
- screen wouldn't go on when moving mouse (IIRC, the led *was* green; screen was just black)
- num-lock on keyboard didn't respond
- no response to ping-requests

The system had crashed. This happened more often, the last weeks. The
same situation is often visible when my system recovers from
hibernation; going down went fine, recovering seems to be ok, but at the
moment I'd expect X to come up the system wouldn't respond anymore.
(sometimes coming up from hibernation works, however)

Note that I use the savage driver because I have a savage8 chip:
eric at dapperdrake:~$ lspci | grep 00:01:  ;  lspci -n | grep 00:01:
0000:01:00.0 VGA compatible controller: S3 Inc. VT8375 [ProSavage8 KM266/KL266]
0000:01:00.0 0300: 5333:8d04

This driver isn't used by default (vesa is), but that's a bug:
