I have 4 PinePhones on which I flashed the same edge image.

On 3 of them everything run fine. but I have one which will crash shortly after being booted.

All phones do have the modem running the latest firmware and I have the anx7688 chip flashed using megis' binary.

The phone is stable using the v20.5 image: 20210219-0007-postmarketOS-v20.05-phosh-5-pine64-pinephone.img.xz

I opened a support request @Pine64 and they asked me to test other distros.

So far, latest version of Mobian and Manjaro works well. I only have a problem with pmOS edge

Any hint would be appreciated.
