Quoting: ShmerlIt's a hard GPU freeze. It renders input unusable (keyboard doesn't react to any keys). You can still access the system over ssh remotely though, but it's not even rebootable, and you can't restart sddm, because GPU is hanging.

Ahh, yeah forgot you'd mentioned that input was ignored too :/

I haven't seen a freeze like that but I'll run some more tests for you - I'll try it on my Polaris card too :) I've CC'd to the bug report.

Thanks! If it would freeze on Polaris on the same system setup, it would confirm it's Polaris specific bug.

OK - I have seen a game 'freeze' with this patched version of Wine but it's similar as mentioned previously and I can unfreeze it unless the game is set to fullscreen = crashed game but not system.

Happens on save.

Quoting: libgradevOK - I have seen a game 'freeze' with this patched version of Wine

You mean with Polaris?

Quoting: libgradevit's similar as mentioned previously and I can unfreeze it unless the game is set to fullscreen

And when it's fullscreen, you can't unfreeze it at all and need a reboot?

No to both, sorry. Just adding FYI.

Quoting: ShmerlIt's possible the newer kernel is the key solution here. I'll try 4.15 when it will be available in Debian testing.

nope, still freezing.. :(

Hm. It must be an amdgpu Polaris specific bug. Weird, but I hope Mesa / kernel developers can do something about it. So far no one responded in the mesa bug. Once we'll collect more info, I can update it with some details about Vega.

https://bugs.freedesktop.org/show_bug.cgi?id=104193

I tested yesterday evening with Vega56 and the patched / hotfixed wine master. I cant use fullscreen due to the loose of input sometimes but windowed it worked. I didnt get a single freeze in about 3 hrs. Will do more testing the next days.

Ubuntu 17.10, mainline kernel 4.15-rc4, Mesa 17.4 Oibaf ppa.

@maspeber: that's likely the game 'freeze' I'm seeing too.

@Shmerl: can you easily compile a later kernel to test?

For reference I installed Win10 on a second disk I had lying around - on Ultra settings (HairWorks off) I'm seeing a solid 60fps @3440x1440 and 100fps @1080p. There's also no slowdown in FPS in town areas - it's very consistent - and the GPU load is showing 100%.
