Description Enrico Scholz 2002-08-08 22:36:59 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):


How Reproducible:

Steps to Reproduce:
1. install beta4 on an MGA450 system (1280x1024, 16bit)
2. call 'glxgears'

Actual Results:

system is dead

Expected Results:

some rotating gears

Additional Information:
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.

Comment 2 Mike A. Harris 2002-12-19 05:35:50 EST
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
