[Mesa3d-users] Radeon Lockups

[vehemens <veh...@ve...>]

I have a radeon (rv250) which hangs when running glxgears.  I enabled debug in
the drivers and found that stopped during processing some light model
parameters.  This is very repeatable.

I'm hoping someone with chip docs might understand what the problem is.

Here is the debug output:
