Hi,
When I try the kernel modules from current drm-git instead of the
stock ones, I get the following crash as soon as compiz launches any
effect with mipmap enabled.
I managed to get a backtrace of the crash, but I got screen corruption
and a full kernel freeze immediately after I quit the debugger.
Nothing particular neither in Xorg nor in kernel logs...
Please let me know if more information is needed to fix this problem.
Regards,
Vincent
