For some time I've been having the following problem:
Regularly ~15 minutes after booting arch the system/kde becomes unresponsive as in 'laggy' and just slow (audio will skip, video framerate drops) to a degree where the system is unusable and has to be rebooted, after which the problem may or may not disappear.
It doesn't seem to correlate with usage as it happens when just listening to music or when having many applications running.
Looking at system monitor/top only shows a slight increase in total cpu usage although 1 core becomes 100%.
Does anyone have a recommendation about how to find the cause of this problem?

try running htop to see what process is eating your core

Ok going to try. Will post when I have info.

X is using the cpu core, but only when moving the mouse and doing stuff with gui.

Yep, try top or htop and iotop to see which processes are running. Alternatively press CTRL+ESC

Yes, did that shows X using a lot of the core. In logs there is:
irq 19: nobody cared (try booting with the "irqpoll" option)
at the time of the slowdown.
So have rebooted with irqpoll option and haven't seen the problem so far, will reboot couple of times to see if the problem has disappeared.

Getting this message now (with irqpoll) instead of the one above
hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj.
Haven't found a solution for it yet, but will post here when found.
