kernel: 4.5.2
mesa: 11.3.0_devel.81287.59156b2

when playing victor vran dmesg gets spammed with MISALIGNED_GPR and
MULTIPLE_WARP_ERRORS, the game runs and i cant notice any particular side
effects from it, i have apitraced it and found the bad
glDrawElementsInstancedBaseVertex call. karolherbst didnt get it when replaying
the trace which is why we suspected its a gk110+ issue.

the call happends in frame 228 and call 372955 according to qapitrace.

trace is a bit big, 372mb compressed.
