Bug#413392: linux-image-2.6.18-4-686: system freeze for `trident' video driver + `pop art squares' screen saver

[Teodor <mteodor@Gmail.com>]

Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-11
Severity: important

Hi all,

I have this problem on my old computer: Intel Celeron, 1100 MHz with a
"Trident Microsystems CyberBlade/i1" video board. I've included this
information because the reported problem does not exist on other servers
used in production (more powerfull).

I'm using Gnome as a desktop environment. When I select the "pop art
squares" screensaver the system freeze after a few minutes. This was not
a problem with linux version 2.6.17, but only with 2.6.18* version.

The X session does not respond to any combination of keys,
Ctrl+Alt+Backspace included.

I don't have the knowledge of debugging kernel crashes. If you can tell
me how to do that I would be glad to offer more information so that this
bug gets corrected.
