http://bugzilla.opensuse.org/show_bug.cgi?id=1179925 Bug ID: 1179925 Summary: Suspend to disk is broken on Thinkpad T495 vega 10 gpu Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: screening-team-bugs@suse.de Reporter: ali.abdallah@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Created attachment 844380 --> http://bugzilla.opensuse.org/attachment.cgi?id=844380&action=edit dmesg failed failed resume from hibernate Upon resume from hibernate on a Thinkpad T495 AMD Ryzen 7 PRO 3700U, the X server is totally frozen, the laptop is not totally frozen as I can connect to it normally with ssh. The issue I belive is on the amdgpu drm driver. Kernel version 5.3.18-lp152.57-default I've tested kernel 5.10.rc7-2.1.g9688120 from head and kernel 5.9.13-1.1.g3dfd18b from stable, suspend to disk works fine with both kernels. Moreover, I've compiled the closest upstream lts kernel (v5.4.82) to the leap kernel and it works perfectly fine. By that I was hoping to diff the changes to identify the fix, but with no success so far. I'm attaching dmesg after the machine resumed from hibernate, it shows the following amdgpu related errors.
