<pre>Both gpu crash dumps are describing same issue.
>From error dump, there is no hung in render ring batch with active head
at 0x0006a028, with 0x01800100 (MI_WAIT_FOR_EVENT) as IPEHR (could it be issue
linked to dpms?)
Moreover we can note that we have ERROR: 0x00000012
Context page GTT translation generated a fault (GTT entry not valid)
TLB page VTD translation generated an error
for reference, batch extract (around 0x0006a028):
