Ubuntu Mate 20.04 kernel issues

GPD Pocket
Ubuntu Mate 20.04, 5.4.0-29-generic

I have installed Ubuntu Mate 20.04 respinned with script and I have plenty of errors in my dmesg. Should I build my own kernel? There is no config file in the repository.

So, I did an upgrade in place (again) from 19.10 -> 20.04, and I am running the same kernel, but I am not getting any ACPI releate errors, nor the rest:

The clock_recovery happend after I opened the lid after it was asleep for a bit.

Not sure if this helps.

Do you have Pocket or Pocket 2? Original GPD Pocket has different hardware. I'm talking about GPD Pocket.

[duckunix]

Sorry, It is a pocket2.

@xzavrel What functional problem do you have? I am testing 20.04.1 images for the Pocket and all devices function correctly.
