Comment= # 4 on bug 95517<= /a> from lumetili@gmail= .com 
OK my 3D accelerated VirtualBox VM just got stuck and journalc=
tl -kf started
spitting out VM faults once a second in a loop, at first there's a:

May 26 01:39:24 carrier kernel: radeon 0000:02:00.0: GPU fault detected: 146
0x0042080c
May 26 01:39:24 carrier kernel: radeon 0000:02:00.0:=20=20
VM_CONTEXT1_PROTECTION_FAULT_ADDR   0x00014482
May 26 01:39:24 carrier kernel: radeon 0000:02:00.0:=20=20
VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x0200800C
May 26 01:39:24 carrier kernel: VM fault (0x0c, vmid 1) at page 83074, read
from TC (8)

And then a:

May 26 01:39:24 carrier kernel: radeon 0000:02:00.0: GPU fault detected: 146
0x0390350c
May 26 01:39:24 carrier kernel: radeon 0000:02:00.0:=20=20
VM_CONTEXT1_PROTECTION_FAULT_ADDR   0x0000C49C
May 26 01:39:24 carrier kernel: radeon 0000:02:00.0:=20=20
VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x1003500C
May 26 01:39:24 carrier kernel: VM fault (0x0c, vmid 8) at page 50332, read
from VGT (53)

It devolves into looping the VGT entry with VM_CONTEXT1_PROTECTION_FAULT_AD=
DR
0x0000C4A<NUMBER> with NUMBER cycling from 0..F
