Red Hat Bugzilla – Bug 71126
Hard-lockup with mga450 and glxgears
Last modified: 2007-04-18 12:45:22 EDT
Description of Problem:
When calling 'glxgears' on an MGA450, the system locks-up (mouse, keyboard and
network are dead).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. install beta4 on an MGA450 system (1280x1024, 16bit)
2. call 'glxgears'
system is dead
some rotating gears
I know that 'glxgears' worked before the beta-cycle but can not tell when it broke.
Hmm. The mga driver, Mesa, etc. hasn't changed since RHL 7.3 at all.
Looks like this was a problem in all releases potentially. It was caused by
an mga DRM kernel module bug which is believed to be fixed in our latest
kernel erratum for 8.0
