VAAPI is broken with 5.13.x linux

Description: With the Linux and Linux-zen packages updated to 5.13.x VAAPI acceleration stopped working on RX6700XT GPU, possibly on other NAVI2 GPUs VAAPI is functional on 5.12.15.

Originally reported on arch forums here: https://bbs.archlinux.org/viewtopic.php?pid=1984257

Additional info:

  • package version(s) linux 5.12.15.arch1-1 (working) linux 5.13.4.arch2-1 (broken) mesa 21.1.5-1 libva 2.12.0-1 libva-mesa-driver 21.1.5-1

  • config and/or log files etc. output of 'vainfo' for Linux 5.12 and 5.13 respectively:

  • link to upstream bug report, if any N/A

Steps to reproduce: Use Linux or Linux-zen 5.13.x packages and observe high CPU usage while video decoding on AMD RX6700 XT (and possibly other RX6x00 cards?) Reportedly OBS fails to encode videos using GPU as well (kindly see reddit URLs in the aforementioned bbs topic) but that's not my use case so I cannot confirm this.
