Created attachment 110808 [details] 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 http://constexpr.org/tmp/serious-dmesg.log (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) This might be related to bug 84500 - 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.
