[ 155.432975] snd_hda_intel 0000:63:00.1: CORB reset timeout#2, CORBRP = 65535 The offending commit is daf8de0874ab5b ("drm/amdgpu: always reset the asic in suspend (v2)"). Commit 34452ac3038a7 ("drm/amdgpu: don't use BACO for reset in S3 ") doesn't help, so the issue is something different. Assuming that to make HDA resume to D0 fully realized, it needs to be successfully put to D3 first. And this guesswork proves working, by moving amdgpu_asic_reset() to noirq callback, so it's called after HDA function is in D3.
