Created attachment 139668 [details] dmesg after resume I still get the backtrace on drm-next-4.18-wip, unfortunately. (note that I have also cherry-picked the last patch from https://bugzilla.kernel.org/show_bug.cgi?id=199693 to make resume work at all) On a side node, I also see that lspci hangs when running this kernel. System: Arch Linux Intel Kably Lake Refresh (i7-8550U), Intel UHD 620 + Radeon Pro WX 3100.
