Hi, I am experiencing gpu crash after resuming from hibernation. After the crash, the screen goes black, and I have to press the power button to hard power off the machine, then restart. I found some bug reports on old kernels, and this one seems to be new. The kernel I am using is: Linux Noah 4.19.12-arch1-1-ARCH #1 SMP PREEMPT Fri Dec 21 13:56:54 UTC 2018 x86_64 GNU/Linux Xorg version: X.Org X Server 1.20.3 X Protocol Version 11, Revision 0 Build Operating System: Linux Arch Linux Current Operating System: Linux Noah 4.19.12-arch1-1-ARCH #1 SMP PREEMPT Fri Dec 21 13:56:54 UTC 2018 x86_64 Kernel command line: BOOT_IMAGE=/boot/vmlinuz-linux root=UUID=96171ef4-cef8-4f06-9617-50d956d76ac8 rw quiet resume=UUID=4ad44aea-31e8-4b0b-97ff-a785e2dde73c Build Date: 25 October 2018 04:42:32PM Current version of pixman: 0.36.0 Before reporting problems, check http://wiki.x.org to make sure that you have the latest version. The output from booting message from journalctl is attached. Nothing is in `/sys/class/drm/card0/error`. I think it has been cleaned away after a restart. Let me know if further information is needed. I have experienced this problem for quite some months, after several arch linux update, meaning kernel update and graphics related library update. Would appreciate to know how to fix it.

No feedback from many months, closing as resolved works for me. Please re-open if issue persists with latest drm-tip https://cgit.freedesktop.org/drm-tip and send dmesg from boot with kernel parameters drm.debug=0x1e log_buf_len=4M? Remember to attach the GPU crash dump file.
