Description Lars Müller 2015-10-08 08:53:31 UTC 
This worked with kernel 4.1.5 and might have started with 4.1.6.

It's always the second resume which fails.

[36592.345861] radeon 0000:01:00.0: ring 0 stalled for more than 10000msec
[36592.345866] radeon 0000:01:00.0: GPU lockup (current fence id 0x000000000075422f last fence id 0x0000000000754257 on ring 0)
[36592.353939] [drm:r600_ib_test [radeon]] *ERROR* radeon: fence wait failed (-35).
[36592.353969] [drm:radeon_ib_ring_tests [radeon]] *ERROR* radeon: failed testing IB on GFX ring (-35).

Full dmesg out attached too.

And it works again with kernel-default-4.2.1-1.4.x86_64

Feel free to close the defect report.

Ah. Nice. Regression fixed upstream.
