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 (with ACS override patches) and ZFS, although as far as I can tell those are not related to the issue, Mesa 17.1.4 with Radeon RX 480. The issue has been around for a while and I sadly do not remember when it first occured, but definitely the entire 4.11.x lineup is affected and I am fairly sure 4.10.x was as well. The issue is way too rare though for me to bisect the exact cause however.
