Comment # 38 on bug 954783 from Jozef Kovac

I found nothing  relevant in log, actualy  nothing at all  in that time  and
never happen again,  tested for couple days, probably another bug, not related
to radeon or need special circumstances.


But i  set up  netconsole(with my old mini 2133 Debian)  and try capture  old
DRI_PRIME=1  bug.

4.1.12-1  immediately after i use DRI_PRIME=1  show:

[  187.561982] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create
device file for dpm state
[  187.562556] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create
device file for dpm state
[  187.563102] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create
device file for power profile
[  187.563643] [drm:radeon_pm_late_init [radeon]] *ERROR* failed to create
device file for power method
[  187.678751] snd_hda_intel 0000:03:00.1: CORB reset timeout#2, CORBRP = 65535

 and nothing more until crash.

4.1.13-5  show  every time when DRI_PRIME=1 is in use.

[  378.149829] snd_hda_intel 0000:03:00.1: CORB reset timeout#2, CORBRP = 65535 


3.16.7-29 

nothing show via netconsole when i use DRI_PRIME=1 and work absolutly stable.





With 4.1.12  crash  everytime  after couple minutes (max 7min),  but 4.1.13-5 
crash 32min/2min/11min  when DRI_PRIME=1  when used.(tested three times)
