I'm running without KMS on my desktop machine, and that's where I get
freezes when I use OpenGL apps (not otherwise). As stated earlier, this
is an Intel 82Q963/Q965 rev 02. This system is x86_64 with an Intel
mobo. I used to have frequent OpenGL freezes (everything dead except the
mouse) which I reported at
https://bugzilla.redhat.com/show_bug.cgi?id=510948. The problem seemed
to go away with a kernel update, to kernel-2.6.30.5-32.fc11.x86_64, but
now seems to have returned in kernel-2.6.30.5-43.fc11.x86_64 and
kernel-2.6.30.8-64.fc11.x86_64,
Hm, I have seen recently random total freezes of that sort
(everything is dead, including a network, and no traces of anything
anywhere) while running xscreensaver-gl* pieces on Fedora 11 desktop
machine but with radeon graphics driver. So maybe this is some
nasty interaction between OpenGL and recent fc11 kernels instead of
an intel driver fault?
Turning off specific xscreensaver-gl executables (sometimes one sees
leftover image fragments on a screen indicating an apparent
offender) was of no help.
