If i enable irqpoll boot option i get lots of these:

What should i try to get rid of this error? System seems to be running good otherwise, Kodi plays videos without problems with 4k upscaling.

Hello.
In case you did not already, first check your kernel options for High Precision Event Timer / Real Time Clock.

Look if CONFIG_PCI_MSI is set, for full explains read NeddySeagoon's comment: https://forums.gentoo.org/viewtopic-p-8170036.html#8170036
