Hi all,

My system panics if glx is enabled in xorg.conf. It happens with both
xorg 6.9 and 7.2 on CURRENT, it didn't happen on 6.2-STABLE some months
ago. Everything works if I remove 'Load  "glx"' form xorg.conf

System panic is:
panic: vm_fault: fault on nofault entry, addr: e41a1000

Full panic with backtrace attached. System configuration at the bottom,
full config files, Xorg log and panic message can be found here:

Any help appreciated. Thanks,

Karol
