Description Stefan Jensen 2010-01-09 18:39:48 UTC

Description of problem:

I can reproduce a serious hard freeze, when gnome-screensaver is enabled.
The machine is completely locked up, requiring a hard reset.

This happens after 10-20 Minutes uptime, when gnome-screensaver is enabled (but not necessary to be active at lockup time.)

If i disable gnome-screensaver and only have enabled "blanking screen after X Min", all is fine. The machine runs ok for severely hours, without any problems.

If the freeze happens, no logs are written, no messages appears, just freeze.
(checked with remote ssh login)

Version-Release number of selected component (if applicable):

$rpm -qa| grep screensaver

fedorainfinity-screensaver-theme-1.0.0-3.fc12.noarch
gnome-screensaver-2.28.0-8.fc12.x86_64
fedora-screensaver-theme-1.0.0-5.fc12.noarch

How reproducible:

Always

Steps to Reproduce:

1. enable gnome-screensaver
2. wait for the machine to hard freeze
  
Actual results:

hard lockup after some time (usually after 10-20 min.) 

Expected results:

no lockup, display screensaver after configured time.

Additional info:

It might be hardware/driver specific, since same version/config on my other machines doesn't show this behavior.

So here are the hardware details of the failing machine:

With F13, there is no problem with this anymore.
