kworker process - guenther - 09-02-2021
Hi folks!
Since the PineTab section seems dead I like to place my post here:
On my PineTab, kernel version 5.10 / 5.13 has the issue that after several minutes after reboot some "kworker" process comes up and eating up 100% cpu.
Kernel 5.9 works fine.
Some inputs? Seems I'm the only one with that issue...
Edit: Its the same on "mobian" and "bookworm"

The lost linked below may have an answer to your problem. Seems like maybe doing a kernel upgrade may be able to solve your issues?

Thank you @ragreenburg for the link. I will dig deeper into the issue but for the moment stick to kernel 5.9...

Best of luck! I am currently on kernel 5.10 and when I tried switching up to 5.13/5.14 I had problems with my brightness. Apparently though the newer kernels are better for battery life.

I switched to kernel 5.13 and did some investigation according to the posted link....
dmesg output gave me:
Code:
musb_bus_suspend 2527: trying to suspend as a_wait_bcon while activeSo it seems it has something to do with the micro usb port. It's also not possible to charge the PineTab or connect it to a pc over that port with kernel 5.13.
I found that link what possibly explains it, but I'm too lazy to read it fully at the moment:

Thankfully there is kernel 5.9
