https://bugzilla.kernel.org/show_bug.cgi?id=199357 --- Comment #7 from Mathias Tillman (master.ho...@gmail.com) --- Wanted to add some more info. The soft lock up will release after approximately 30 seconds, but after a few seconds it will lock up again and repeat. Looking at the kernel log, it seems that when the lock up happens, it takes an abnormally long time to reach the dm_pflip_high_irq function which is supposed to trigger the flip_done message. I've attached a new log with my added logging in case that helps. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

Unless a fix is at least on the horizon, since this commit introduced multiple issues, it would be nice to our users to revert it for the time being, then re-apply it when it's safe. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel

https://bugzilla.kernel.org/show_bug.cgi?id=199357 --- Comment #5 from Harry Wentland (harry.wentl...@amd.com) --- I've no idea why this causes "flip_done timed out" and locks the system right now, but we're currently also dealing with some more fallout from that change, in particular blinking/flickering display if redshift/nightlight is on. I'm reluctant to just revert the offending commit as it's not incorrect but seems to expose some other flaws in our atomic check/commit implementation. -- You are receiving this mail because: You are watching the assignee of the bug. ___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
