Did you try some of the previous 4.4 kernels (eg 4.4.5 etc) that have appeared in updates_testing over the past 6 months? Ie, do you have a feeling as to when this broke? CC:
(none) =>
unruh nope, sorry, I don't have testing repo enabled. So can even be regression from 4.2 or 4.3 kernels if you can point me to a package archive, I could try with the other kernels... unfortunately this is not the only regression - when plugging in or out an external monitor (in this case a TV using a min-displayport â hdmi adapter), the backlight controls are likely to get dysfunctional. pressing keys shows OSD and claims to switch values, but that has no impact on actual panel brightness :-( Please attach journalctl -b output from both working 4.1.15, and from a non-working 4.4.13 and the output of lspcidrake -v CC:

lspcidrake -v wiht 4.4.13 kernel
difference to 4.1.15 output is (besides kernel version string in hub lines) only that "intel_pch_thermal" was previously listed as "unknown", apart from that identical.

gm2.asp using vaapi-driver-intel from cauldron seems to remove this issue Mass-reassigning all bugs with "kernel" in the Source RPM field that are assigned to tmb, to the kernel packagers group, because tmb is currently MIA. Assignee:
tmb =>
kernel Please disregard comment 8. Turns out that successful playback was due to mythfrontend falling back to CPU decoding on failure to initialize the vaapi driver. Sorry about the misinformation However, installing both lib64va1 and vaapi-driver-intel from cauldron does allow at least mythfrontend and vlc to use vaapi. (problem with only installing the driver was incompatible API version) Furthermore, building and installing latest version (1.7.2) of those components on mga5 removes a log about failure to open /usr/lib64/dri/hybrid_drv_video.so (which, as far as I understand, is of no use for my hardware anyway) FYI: works OK on Mga6, so kind wfm now... bob interlacer is broken though (gives vertical jitter), but you can use the superior motion-compensated backinterlacer Summary:
