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.

Weird.
Comment 2 Mike A. Harris 2002-12-19 10:35:50 UTC 
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
