Crash dump from /sys/class/drm/card0/error
Kernel: kernel-3.16.0-0.rc3.git3.1.fc21.x86_64
MESA: mesa-dri-drivers-10.2.2-3.20140625.fc21.x86_64
Xorg: xorg-x11-server-Xorg-1.15.99.903-100.fc21.x86_64 (patched with [PATCH]
dri2: Use the PrimeScreen when creating/reusing buffers)
Playing Second Life with radeon GPU offload to Intel GPU running with export
LIBGL_DRI3_DISABLE=1 since DRI3 in this Mesa has no DRI3 DRI_PRIME support yet.
Kernel spit out this error:
[ 293.644011] [drm] GPU HANG: ecode -1:0x00000000, reason: Command parser
error, iir 0x00008010, action: continue
[ 293.649949] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 293.649949] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 293.649949] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 293.649949] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
