i915 error state
While running Vkcube, I get hangs after a few seconds.
The command stream is full of invalid instructions :
--- batch buffer (rcs0) at 0x00000000 00021000
unknown instruction ff7b7b7b
unknown instruction ff7b7b7b
unknown instruction ff7b7b7b
Vkcube also ends up crashing and under valgrind I managed to get this couple of
backtraces :

Unfortunately it seems it's just valgrind rereading the corrupted batchbuffer,
so still not sure who's responsible for the corruption.
This is using mesa master :
