--- Comment #8 from [email protected] --- During the many cycles of “printk, compile, reboot, suspend, resume, crash X” I’ve found that the problem may have to do with the fact that I load radeon.ko during my initramfs before attempting resume by echoing into /sys/power/resume or /sys/power/tuxonice/do_resume. If I do *not* load radeon.ko into the “booting” kernel (i.e., the one which is then replaced by the “resuming” kernel), I couldn’t reproduce the crash. Furthermore, I do *not* get these four messages from the “resuming” kernel about a lockup: [ 864.574325] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec [ 864.574328] radeon 0000:01:00.0: GPU lockup (waiting for 0x0000000000000004 last fence id 0x0000000000000002) [ 864.574331] [drm:uvd_v1_0_ib_test] *ERROR* radeon: fence wait failed (-35). [ 864.574334] [drm:radeon_ib_ring_tests] *ERROR* radeon: failed testing IB on ring 5 (-35). -- You are receiving this mail because: You are the assignee for the bug.
