Subject: Re: [git pull] drm fixes for 6.15-rc1

I was going to report this separately, but then the pull came in, so
I'm just replying to that one instead...

Does any of this happen to fix this (repeated a couple of hundred
times each time):

  [drm] scheduler comp_1.1.1 is not ready, skipping
  [drm] scheduler comp_1.3.0 is not ready, skipping
  [drm] scheduler comp_1.0.1 is not ready, skipping

which seems to happen on my machine when the display goes to sleep and
then comes back from low-power state.

It also seems to make the power resume quite a bit slower. Everything
still seems to *work*, just annoying messages and an extra several
seconds of black screen...

This is on my threadripper with the same ancient "Sapphire Pulse RX
580 8GB" or whatever it is. lspci calls it "Ellesmere [Radeon RX
470/480/570/570X/580/580X/590] (rev e7)"

I will be pulling and testing, but I thought I'd mention this issue regardless.
