Created att= achment 132600 [details] dmesg with lockup warning at the end An amdgpu syscall, called by plasmashell, appears to deadlock randomly and freeze X.org completely. Several graphics processes, plasmashell and X.org = are left stuck in D-State. Everything else continues to operate correctly, including audio, networking, etc.. The issue seems to appear more frequently whilst running games, although I = am unable to find any particular pattern to it. Running Arch Linux with a custom compiled linux-zen kernel, Mesa 17.1.4 with Radeon RX 480. The issue has been around for a while and affects all 17.1.x releases so far, however I am not certain for how long it has been around. = The issue is way too rare though for me to bisect the exact cause however. Once I get another freeze I will see if I can get any userspace thread dumps from plasmashell and possibly other processes as well as any logs containing something interesting. (This may take anywhere from a few days to weeks due= to the random nature of the lockup) (Also, just to clarify, this is not directly related to https://bugs.freedesktop.org/show_bug.= cgi?id=3D101294, this occured before and after that issue being fixed.) Originally reported at, as this manifests itself in the kernel first: https://bu= gzilla.kernel.org/show_bug.cgi?id=3D196291
For reference, checking on the fence status it looks like one = of the SDMA engines is hung.
Sadly could not find any useful information out of various pro= cess logs, in particular Xorg.0.log contains nothing error related. The only thing that is somewhat interesting is that some processes that ought to use OpenGL do not= end up stuck in D state, whilst it appears only specifically plasmashell and Xo= rg get stuck. (Obviously no graphical output works on any other processes eith= er anymore, nor can one switch virtual terminals anymore with Xorg being dead.) If anyone knows any specific things that may be useful to debug, I can see = if anything helps.
I have not encountered the random hang for a while now (specif= ically after turning off slideshow in plasmashell) and am unaware of any reliable way to reproduce this exact issue, so not entirely sure if this report being left = open is of much use. However recently I also get a GPU crash by running Overwatch in wine (using= a patched version), but as I said, I am not sure if this is even remotely rel= ated (besides both causing a GPU crash) at this time.
