1)lsbrelease -rd:
Description: Ubuntu 21.10
Release: 21.10
2) i dont know if it is the kernel or an KDE problem, but i would guess the kernel
3) Use the touchscreen without errors
4) The following Error-Message pops up, sometimes(!) when i use the touchscreen. It is not every time and i dont know how to re-create it:
kernel: watchdog: BUG: soft lockup - CPU#3 stuck for 108s! [irq/158-WACF220:257]
...
complete error-message is an attachment
---
When this happens i cant use my touchscreen or touchpad. It is stuck for ~30 seconds. I can still use my keyboard.
*Edit:
now it also affected my Keyboard and i couldn't use it. After it worked again, i could not scroll up/down with my touchpad (see "complete-error-report-2")
