When running Unigine Heaven windows version benchmark my computer always freezes at scene 8. Freezing happens when using Tomb Raider 2013 windows version benchmark too. Ssh connection works but I can not kill the hanging app and virtual terminal and keyboard does not work. Rebooting via shh does not work either. No dmesg or other log events can be seen when this happens. Running native Linux Heaven benchmark or other native games runs ok. glxinfo | grep OpenGL OpenGL vendor string: X.Org OpenGL renderer string: Gallium 0.4 on AMD POLARIS11 (DRM 3.3.0 / 4.7.0-g1ed6b7d-dirty, LLVM 4.0.0) OpenGL core profile version string: 4.3 (Core Profile) Mesa 12.1.0-devel - padoka PPA OpenGL core profile shading language version string: 4.30 OpenGL core profile context flags: (none) OpenGL core profile profile mask: core profile OpenGL core profile extensions: OpenGL version string: 3.0 Mesa 12.1.0-devel - padoka PPA OpenGL shading language version string: 1.30 OpenGL context flags: (none) OpenGL extensions: OpenGL ES profile version string: OpenGL ES 3.1 Mesa 12.1.0-devel - padoka PPA OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.10 I will not use amdgpu-pro driver, because wine-staging csmt feature does not work with it and amdgpu-pro does not support latest kernels.
This is more likely a mesa issue than a kernel issue.
So tell your driver page for non ubuntu users what mesa and kernel works so that rx460 has best performance, works with wine-staging and gallium nine and Rosegarden plays midi and sw synth tracks. I have now 2 days searching and testing and not found. After 4.7.8 Rosegarden does not work and before that rx460 performance is bad. My current amd-staging-4.7 have sudden panics boot and next I try drm-next-4.10 where Rosegarden do not work but I will see how are the graphics and system stability.
What version of mesa are you using?
I have tested Mesa 12.1.0-devel - padoka and Oibaf ppa and Debian testing 12.0.3-1. Same problem with kernel that have latest powerplay code. Now I am using kernel 4.7.8 that has a poor graphics performance but seems to stable and Rosegarden works. My RX460 is as fast my A8-7600 that I had before. Amd linux drivers have been going down hill since I bought the A8-7600 two years ago, Then it was a surprise how well it worked with Catalyst. Only solution I found now is to install win10 to my test partition If I want to enjoy rx460. At the same time my kid plays fine with Nvidia 750ti and Debian testing while I am searching drivers.
I did not have KVM support enabled in the kernel when using Kaveri. Enabling it seems to stabilize amd-stagin-4.7 kernel so that sudden reboots do not happen, I hope. TR 2013 I could tune so that the benchmark works but Heaven still hangs my machine, now in the end of the benchmark. Padoka ppa mesa and wine-staging used.
Can you post a dmesg log of when the hang happens?
There is just boot traces in dmesg, journalctl and Xorg.0.log when my computer desktop hangs and checking with ssh.
I made my kernel slower by enabling debug and setting cpu timer from 300Hz to 250Hz. Now my desktop does not hang with TR 2013 and Heaven benchmarks although Heaven hangs when using 8x antialising but I can kill that. Amd should put their .config to public and highlight the following kernel settings: IRQ Quirks, Amdgpu PowerPlay, KVM, use a debug kernel and 250MHz timer.
Now when I am playing TR 2013 with wine-1.9.21 (Staging) csmt enabled, gaming will will hang my machine when having fast actions. 10-20 minutes gaming is possible without rebooting. Using 64-bit ubuntu server kernel from here: http://www.yourownlinux.com/2016/10/how-to-install-linux-kernel-4-9-rc1-in-linux.html Playing the game at 1920x1200 normal settings. I have played the game many times with A8-7600 and amdgpu kernel driver without hanging. The hardware and software has been the same except now I have carrizo cpu and polaris gpu. My hardware: XFX RX460 2GB DDR5 Amd X4 845 Carrizo cpu Asus A88XM-E motherboard 8GB 2133MHz ddr3 SanDisk SDSSDA240G OS: Debian testing Xfce with Padoka ppa Mesa 12.1.0-devel. No events in logs, because hanging happens so fast.
Inspired by internet discussions of the amdgpu driver, I played Team Fortress 2 native version from Steam and the game hangs my machine in the practice mode in couple of minutes. I need to reboot like I need to with TR2013 windows game. Amd should increase the stability of this driver.
I made TF2 gaming stable by disabling kernel debugging and setting cpu timer to 300Hz.
With Tomb Raider Legend the game hangs Xserver in one minute when playing at fullhd.Dropping resolution to 720p allows to play stable. drm-next-4.10-wip and Oipaf ppa mesa from yesterday used. There is no matter if csmt in wine-staging is enabled or not.

I tested latest drm-next-4.10-wip today that have couple of more patches that yesterday. Still Xserver hangs when playing Tomb Raider Legend at full hd. With dmesg, I have these errors at boot: [ 3.466266] amdgpu 0000:01:00.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff [ 3.466706] ATOM BIOS: C99401 [ 3.479722] [drm] amdgpu: irq initialized.

One hour ago published Oibaf Mesa fixed Xserver hanging when playing TR Legend at fullhd. https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers/+packages
New Mesa did not fix this. Playing at fullhd TR Legend still hangs xserver in 3 minutes. Tried 2 times, same effect. Works as good as with an 300Hz overclocked non debug 4.9-rc2 kernel from kernel.org, where Unigine Heaven windows benchmark runs ok. I do not know why my first gameplay after updating mesa was long and did not hang xserver.
Recent drm-next-4.10-wip and Mesa changes have made wine-staging gaming more stable. TR 2013, Legend and Underworld works now at my monitor native 1920x1200 resolution. To play TR 2013 without desktop hanging, I needed to disable Post Processing, Anti-Aliasing, SSAO and set Texture Filter to Bilinear. Other settings can be ultra and high. I thank driver developers for fast fixes.
