I just installed Kubuntu after being a Windows user for all my life. Only been working with Linux through terminal on servers.
Anyway, I feel like my computer is working harder than normal when just being idle in Kubuntu. I checked the system monitor and it shows nothing crazy (only kworker:0.2 using 12%).
However, when checking the CPU statistics I can see that one core is allways close to 100%. Is this normal or not? All the other cores are relaxing at 0-4%.
I did a perf trace and found this:
46,63% 46,37% kworker/0:2 [kernel.kallsyms] [k] pci_conf1_read
I just need to know if everything is normal here so I can relax or if its hogging uneccesarily at my CPU
