Created attachment 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=101294, this occured before and after that issue being fixed.) Originally reported at, as this manifests itself in the kernel first: https://bugzilla.kernel.org/show_bug.cgi?id=196291
