Pinephone Mainboard Replacement Issues

[p1x3l3d]

Hey StringBean,

Unfortunately I'm not commenting with a solution here, but because I also seem to have (stability) issues with the new 3GB Pinephone CE mainboard that I received last week. It replaced my Braveheart Edition 2GB mainboard which also worked very well. Hopefully with one more person reporting similar issues this thread will gain some more gravity?

I've attempted to boot several images with it; Mobian, postmarketOS and Manjaro Phosh + Plasma Mobile. The first two do boot and seem to work, however with those I've also had the occasional unwanted reboot. The Manjaro images do not boot up to a usable GUI at all however. They always and up showing a stack trace or a black screen on the phone's display. I managed to grab some output produced during boot through the serial console connection though. Sometimes it boots far enough and a cli login prompt is presented and can be interacted with. At the Manjaro forum I've made an elaborate post explaining the situation in more detail which can be found here.

I think the most interesting take-aways are this one, the first few lines while booting (and failing):

Code:

At that point the phone has crashed and is completely non-responsive.

And these might also be interesting, they are last lines shown when attempting to boot, failing and shutting down immediately afterwards:

Lastly, I also noticed an error while I think it's trying to initialize the modem. This shows up in case the phone does boot up to a login prompt accessible through the serial console:

Unfortunately I'm not proficient enough with Linux boot processes or these hardware specifics to see if these errors might be caused by hardware defects. Perhaps someone else has some meaningful insights?
