            Bug ID: 200869
           Summary: UVD cause amdgpu crash on CIK: [amdgpu]] UVD not
                    responding, trying to reset the VCPU

attachments from the firepro machine

no VDPAU or VAAPI is possible with my firepro w5100 card, using a bonaire chip.
The module needs to be loaded 3 times before the card is initialized
successfully.  3 times is not a random number: it's every time like that:
- First time, the UVD is failing,
- Second time, the SDMA is failing
- Third time, the GFX ring buffer test fails, but the GPU works
when using HW acceleration, the GPU crashes again, and the process turns to
zombie

Attached:
- dmesg log
- Xorg log
- ps aux

--- Comment #1 from Janpieter Sollie (janpieter.sollie@dommel.be) ---
Small update:

When booting the module with the following parameters:
amdgpu si_support=0 gpu_recovery=1 dpm=1 dc=0

I still need to load/unload the module 3 times, but it works for non-1080
videos.
For 1080 videos, the mplayer already draws a black screen (didn't do that
before), but does not show anything in the black window.  
Killing the mplayer process with kill -9 also kills the process properly.
These steps do not result in any extra information in dmesg, though.

2nd update:
after a double check of /sys/module/amdgpu, it turned out that the parameters
for amdgpu were not applied at all when put in /etc/modprobe.d/options. I
turned lilo into the following startup string:
amdgpu.dc=1 amdgpu.audio=1 amdgpu.si_support=0
which seems to work properly.  Sorry for the incorrect bug reporting.
