Red Hat Bugzilla – Bug 57527
xscreensaver crashed kernel: mga oops
Last modified: 2007-03-26 23:50:25 EDT
Xscreensaver seemsed to freeze; mouse moved but keyboard would not react.
Sshing in worked. Xscreensaver was using 99.9% of resources; perhaps a trigger here?
Killing it didn't help.
On kernel log, there was a crash dump (a few modules have been rebuilt, but I doubt that
affects mga in question); text attached.

This problem is believed to be fixed now, and affected pretty much
all DRI enabled drivers. Please test the latest rawhide X and
kernel either using the Red Hat Linux (Null) beta, or once the new
release of Red Hat Linux is completed and released. After testing
this out with our latest kernel/X, please provide updated status, and
if the problem persists, please attach your X server log and config
Most likely however, the problem will not occur in the lastest

still oops with 2.4.18-24 kernel XFree86-126.96.36.199
The reported Bug occures again on Kernel 2.4.18-24 / RedHat 8.0
what kind of modules are you using ?
Pekkas) Can you please update this report with your own current status
with the latest erratum kernel, etc.?
I do not recall seeing this recently, but will keep my eyes open. Currently
(kernel update is pending a reboot.)
ulrich) While your oops report contains mga related bits, it does not
appear to be related to this particular bug report IMHO, and should be
considered a separate bug report. Please file a new bug report in
bugzilla if you wish to have it tracked. As Arjan noted however, your
kernel is flagged as tainted. Before filing a new bug report to track
the oops issue, ensure that you are not using any 3rd party kernel
modules of any kind.
pekkas) Ok, I'm closing this as resolved in errata kernel for now then,
however if the problem recurs, feel free to reopen.
