After booting into a known working kernel, the journald of the failed boot indicates that the amdgpu driver segfaulted after the login manager started. I'll append a kernel stack trace to this bug report in a moment. As part of bisecting and then digging into this I also tried a non-RT kerne= l as well as manually setting `gpu_sched.sched_policy=3D1` which should correspo= nd to the deadline GPU scheduler instead of the `gpu_sched.sched_policy=3D0` that= I usually set (and which, I believe, set the RR scheduler). However the only = fix I found was to revert the commit, which is what I'm now running on top of current git master (commit 7449f86bafcdb588422bb14a4babfd285e723670). All crashes seem very similar with the only difference being that the one non-RT build I tested lacked the `? dc_stream_get_scanoutpos+0x116/0x140 [amdgpu]` line but otherwise they all look the same to my pleb eyes. I tried CC'ing the relevant people but seems their AMD addresses are not kn= own to the kernel infrastructure --=20 You may reply to this email to add a comment.
