Kernel log
When playing Portal2 or L4D2 with DRI3 on, after some quite short time game
locks and kernel log has the following messages.
0000:01:00.0: GPU fault detected: 147 0x00060802
0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00000000
0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x06008002
0000:01:00.0: VM fault (0x02, vmid 3) at page 0, read from '' (0x00000000) (8)
My hardware is HD7750, Linux is 4.9.0-rc4, rc1 was also affected. Mesa version
is 13.1-dev, 13.0 and 13.0-rc2 were affected as well.
I have the same issue with radeon kernel driver as well (Linux 4.6-4.9, Mesa
12.0 - 13.1 dev), but in this case kernel log is clear. So, possibly, this
issue is in Mesa code, or in code ported from radeon.ko. With DRI2 I don't have
this issue in any case.</pre>
