Radeon HD 6570 resume issue with linux 3.10 (regression)

[Patrizio Bassi]

Hi All,

on my Core2 (x64) system with linux 3.9 i could suspend to disk (and
resume) correctly from my kde 4.10 environment.

Just upgrading to linux 3.10 resume got broken due to GPU driver.

more infos:
1) suspend to ram works perfectly (resume too of course)

2) suspend to disk works, resume seems working for few seconds, than X
closes, KDE restarts a couple of times than freezes.

3) with ssh i can see system is still alive, but if i kill and restart
X it gets stuck again

4) with ps i can see a huge number of kworker processes (they count
around 85...)

5) dmesg (attached) shows errors

[  209.334052] radeon 0000:01:00.0: GPU lockup CP stall for more than 10000msec
[  209.334055] radeon 0000:01:00.0: GPU lockup (waiting for

[  209.334064] [drm:radeon_ib_ring_tests] *ERROR* radeon: failed

and then a long list of

[  323.215792] radeon 0000:01:00.0: ffff88010f45a800 pin failed
[  323.936780] radeon 0000:01:00.0: ffff880120567c00 pin failed


I'll be ready to test any patch
