--- Comment #14 from Andy Furniss <adf.lists at gmail.com> ---
Been testing vce and there is an issue with auto.
This is not just this kernel, I've been back and now I have a script to test
lots of runs, I can reproduce on older kernels + current fixes as well.
The issue is that it will hang, at this time I am apparently OK in that I can
use desktop normally. There is no hung task timeout. If I kill the gstreamer
process it won't return, then I may get a hung task trace.
Whether I kill gstreamer or not, quitting X or a VT switch will lock up
display.
This only happens when
/sys/class/drm/card0/device/power_dpm_force_performance_level is auto.
If it's high or low I can repeatedly run vce encodes OK - I have tested > 1000.
On this kernel and fixes it only takes < 5 runs to lock with the same test.
On an older kernel it lasted for 25 runs (which is I guess why I didn't hit it
in "normal" testing + I often forced high for bench marking anyway)
