Comment 1 emersion 2019-06-14 11:06:38 UTC

(This happens on boot on re-icl-u. After this, `sudo aplay -L` doesn't show any HDMI/DP audio devices.)

Comment 2 Chris Wilson 2019-06-14 11:07:51 UTC

Please do confirm bugs on the current upstream drm-tip before reporting upstream.

Comment 3 Chris Wilson 2019-06-14 11:09:19 UTC

The dmesg also required drm.debug=0x2 to get the right information here.

Comment 4 Lakshmi 2019-06-28 11:43:23 UTC

Simon, can you attach the dmesg with drm.debug=0x2 parameter?

Comment 5 emersion 2019-07-08 11:20:01 UTC

Cannot reproduce anymore.
