dmesg output with the GPU fault errors filtered out
Running Serious Sam 3 or The Talos Principle spams dmesg with thousands of
these errors:
[ 6001.212237] radeon 0000:01:00.0: GPU fault detected: 147 0x02528801
[ 6001.212243] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR
0x0FF02192
[ 6001.212246] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS
0x12088001
[ 6001.212249] VM fault (0x01, vmid 9) at page 267395474, read from TC (136)
There are also a few "Packet0 not allowed" errors (followed by a hex dump):
[15446.473341] radeon 0000:01:00.0: Packet0 not allowed!
So far it's only these errors in dmesg - I haven't observed any actual
rendering issues, crashes, GPU lockups because of this.
I have only attached a filtered kernel log with the GPU fault errors removed -
the full log is available at <a href="http://constexpr.org/tmp/serious-dmesg.log">http://constexpr.org/tmp/serious-dmesg.log</a> (140
MiB).
Both of these games use the Serious Engine 3.5 (Serious Sam 3) or 4 (The Talos
Principle). This is also reproducible with The Talos Principle Public Test
which as of now is still available as a free download on Steam.
Kernel: 3.18.0-gentoo
GPU: Radeon HD 7950
Driver: radeonsi, Mesa 10.5.0-devel (git-ff96537)

href="show_bug.cgi?id=84500">bug 84500</a> - however those spurious Packet0 have been
gone for a while now with updated Mesa - now I got them again but only while
running Serious Engine games.</pre>
