Description Martin Peres 2019-08-13 07:28:36 UTC 
It has been a while, but it seems like snd_hdac_bus_process_unsol_events is again giving us null pointer dereferences:

Comment 1 Takashi Iwai 2019-08-13 15:33:33 UTC 
I'm not sure how hdmi_unsol_event() gets called for the Intel chip, as this shouldn't be handled at all.  Maybe it's some race at registration where the function is triggered before the audio component is fully set up.

The patches below are potential (or better to say, hopefully) fix for this.

Thanks! Asking someone to apply them on our tree for testing!
Comment 5 Takashi Iwai 2019-08-15 09:51:55 UTC 
FWIW, I've put them to sound.git tree for-next branch.  Today's linux-next should contain them.

Thanks! They have not yet flowed to drmtip. I'll check after the next rebuild if we need to apply the patches or if they would come automatically.

Looks worse now:
