https://bugs.freedesktop.org/show_bug.cgi?id=105018 --- Comment #30 from L.S.S. --- EDIT 2: I couldn't reproduce the issue on 4.17 this time even after 2 wakeups. However, the issue I encountered was similar (system apparently froze when trying to wake up the screen). After looking into it, I found that along with the errors that showed up like that in Comment 16 (which did not crash the system), there was an additional "kernel BUG" related to dm_update_crtcs_state which was called by amdgpu_dm_atomic_check, but the log appeared to have been cut (the log entries between the two errors were apparently unrelated to the error so I did not include them, and the new error began with a "--[ cut here ]--"). This additional error (not 100% reproducible) might be what actually crashed the system that time. -- You are receiving this mail because: You are the assignee for the bug.
