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?
