--- Comment #2 from yann <yann.argotti at intel.com> ---
>From your error dump, we can see the following error.

ERROR: 0x00000101
    TLB page fault error (GTT entry not valid)
    Cacheline containing a PD was marked as invalid

in, render ring we have 
  FAULT_REG: 0x000000c5
    Valid
    Unloaded PD Fault (PPGTT)
    Address 0x00000000
    Source ID 24

This is not happening in batch (checked in the render ring section).

Chris, do you think this could an issue with hw memory? Any direction to look
for?
