HDMI doesn't work anymore with linux-postmarketos-allwinner from master (doesn't affect everybody)

Describe your issue

For me, HDMI doesn't work anymore with the latest kernel on master, as of writing 5.10.0_git20201214-r0. I had it working with the same phone (PinePhone pmOS CE) and monitor with 5.9.10_git20201123, as reported here.

This doesn't seem to affect everyone, @MartijnBraam and @dylanvanassche have verified that it works for them with 5.10.0_git20201214-r0:

On what environment did you encounter the issue?

How did you get postmarketOS image?

I built it using pmbootstrap (regular build, the only thing out of ordinary is that I tested using the de_DE locale).

I flashed a new edge image this past saturday into my pinephone CE and the hdmi works perfectly fine with my LG TV (it doesnt with the factory image).

By Dahrkael on 2021-01-18T18:12:06

Thanks for the feedback, @Dahrkael!

Yesterday I tried it again myself, with current postmarketOS edge, and couldn't reproduce the issue either. I also haven't heard from anybody else that this happened, so closing.

Hmmm this problem is back and it affects more kernels (5.11.10 in this case)! I noticed that I could have the USB devices working from the dock, the display gets recognized in Settings, but nothing on the display. dmesg is spammed with:

[ 1250.768430] musb_bus_suspend 2527: trying to suspend as a_wait_bcon while active

This goes away when the dock gets unplugged. I pinged megi on Matrix/IRC, let's see what happens.
