1)lsbrelease -rd:
  Description:    Ubuntu 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]

When this happens i cant use my touchscreen or touchpad. It is stuck for ~30 
seconds. I cant still use my keyboard.
