Hi All, Fedora has a (opt-in) system to automatically collect backtraces from software crashing on users systems. This includes collecting kernel backtraces (including once triggered by WARN macros) while looking a the top 10 of the most reported backtrace during the last 2 weeks report from ABRT: https://retrace.fedoraproject.org/faf/problems/ I noticed the following backtrace: https://retrace.fedoraproject.org/faf/problems/13904/ which has been reported 160000 times by Fedora users who have opted-in during the last 14 days. The ABRT symbol resolution points to amdgpu_dm_backlight_update_status: 1 amdgpu_dm_backlight_update_status amdgpu 0xb4 2 amdgpu_dm_backlight_update_status amdgpu 0xb4 3 amdgpu_dm_backlight_update_status amdgpu 0xb4 4 amdgpu_dm_backlight_update_status amdgpu 0xb4 5 ? amdgpu_dm_backlight_update_status amdgpu 0xb4 6 amdgpu_dm_backlight_update_status amdgpu 0xb4 7 amdgpu_dm_backlight_update_status amdgpu 0xb4 8 drm_sched_job_timedout gpu_sched drivers/gpu/drm/scheduler/sched_main.c 289 But the backtrace from dmesg points to something else: RIP: 0010:dcn10_get_dig_frontend+0x76/0xb0 [amdgpu] Code: 39 44 89 c0 48 83 c4 08 c3 41 b8 05 00 00 00 83 f8 20 74 ed 41 b8 06 00 00 00 83 f8 40 74 e2 41 b8 04 00 00 00 83 f8 10 74 d7 <0f> 0b 41 b8 ff ff ff ff 48 83 c4 08 44 89 c0 c3 45 31 c0 83 f8 01 RSP: 0018:ffffa376c2dffca8 EFLAGS: 00210297 RAX: 0000000000000000 RBX: ffff8ecf6b760000 RCX: 0000000000000008 RDX: 0000000000000000 RSI: 000000000000596f RDI: ffff8ecf6db20000 RBP: ffff8ecf6a187000 R08: 0000000000000000 R09: ffff8ecf6f88fc00 R10: 0000000000000001 R11: 0000000000000006 R12: ffff8ecf727ec200 R13: 0000000000000006 R14: ffff8ecf6f982800 R15: ffff8ecf6e749200 FS: 0000000000000000(0000) GS:ffff8ecf7e9c0000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007fb5fb4a8000 CR3: 0000000356446000 CR4: 00000000003506e0 Call Trace: dcn10_init_hw+0x6ed/0x930 [amdgpu] dc_set_power_state+0xf5/0x140 [amdgpu] dm_resume+0x328/0x500 [amdgpu] amdgpu_device_ip_resume_phase2+0x52/0xb0 [amdgpu] ? amdgpu_device_fw_loading+0x9f/0x110 [amdgpu] amdgpu_device_gpu_recover.cold+0x8c1/0xf62 [amdgpu] amdgpu_job_timedout+0x11c/0x140 [amdgpu] drm_sched_job_timedout+0x72/0xf0 [gpu_sched] process_one_work+0x1b4/0x370 There also is this bugzilla about this: https://bugzilla.redhat.com/show_bug.cgi?id=1929746 from today And a whole bunch of others: https://bugzilla.redhat.com/buglist.cgi?quicksearch=amdgpu_dm_backlight_update_status Any help with resolving this would be much appreciated.
