Description Stefan Dirsch 2014-03-11 14:43:51 UTC

This is seen with render offloading on Radeon with any Intel gfx (Nvidia not
tested)

"DRI_PRIME=2 glxinfo" crashes X. It happens with any program. It happens only
if rendering is offloaded. Without association the Intel gfx is accessed.

Please attach the Xorg log file and the output of dmesg, and if possible a gdb backtrace of the crash.

Michal Srb fixed this meanwhile and sent a patch to the xorg-devel list.
