Hey,
I'm experiencing a kernel panic whenever I run glxgears, or it would
seem when I try to run other gpu-related tasks. I first noticed this
when playing video via the application 'mpv', after a couple of
seconds of video the system freezes!! I've got the trace output for
that as the time delay allows me to switch out of X11 to a console
before the system crashes. Anyway after this I tried 'glxgears' and
that crashes immediately (so I'm unable to get the trace, but it
sounds like it's related?).
Just wondering if anyone else is able to reproduce this on their
powerbooks / other g4 macs, does glxgears work for you?

What is the actual panic message?
For the archives the trace was:

The panic message is:
panic: mtx 0xe024cc50: locking against myself
I forgot to mention that this is new in 6.8, I can run glxgears/play
video with mpv fine using 6.7.
