Display problem, doesn't work when cold booted

[ibriski]

If I cold boot the device the display doesn't work - probably isn't initialized correctly. Then I log in using SSH and issue a reboot command the display starts working correctly (framebuffer device works).

If I look at the dmesg output when cold booted I see that there is an error which doesn't appear if the phone is warm booted:

I can confirm this issue, it has been bugging me forever.

I can reproduce the problem without any effort. I'm currently running linux-pinephone 6.6.9-1

Sometimes I need to do more reboots before the screen starts working.
