Greetings everyone.
I am experiencing the kworker issue where a kworker is using 100% of a given core.
This behavior was only observed after having installed a new water cooler, to replace a cooler that had died. (Sealed closed loop device from Corsair)
The processor is staying around 40 degrees celsius as reported by the MB UEFI interface. (ksysguard shows between 29 degrees and 30 degrees, when running KDE 4)
I am unable to isolate a cause, or resolution for getting the kworker usage back to normal.
Very basic description of specs are as follows:
AMD FX-8350 (not overclocked)
32GB Corsair memory (1866Mhz non-overclocked)
Sabortooth 990FX MB
I have checked the locations for interrupts which has been indicated online, however, I do not have any specific interrupts that are showing as even having a high integer value to unset.
Here is the result of running the referenced command to view interrupts.
