there is already a similar report at kernel bugzilla, but nobody took notice: https://bugzilla.kernel.org/show_bug.cgi?id=190971 It's a kernel bug, first seen with linux-4.20 on my Carrizo. I don't have a testcase for reproducing, so it's hard to bisect. Sometimes it happens multiple times a day, with every suspend-resume cycle. Sometimes the machine works for several days with at least two suspend-resume-cycles per day.
Still an issue with linux-5.0.0-rc6
Please post your full dmesg log and an Xorg log if applicable. I see you have a partial log for the problem on the kernel bugzilla but it'd help to have a full one.
Created attachment 143380 [details] dmesg log full dmesg log from boot until a hang attached
Anything I can do help debugging this? It's still an issue with 5.1-rc1 and really annoying.
Created attachment 144083 [details] dmesg log from suspend->resume->suspend->resume When this bug occurs, from sddm it is possible to put the system into suspend again via hotkey. In most cases the second resume works. Attaching a dmesg output from such a suspend->resume->suspend->resume cycle. Maybe this helps debugging this.
ping? still an issue with kernel 5.1
