Use
latency-histogram --nobase --sbinsize 1000 --show
There are a lot of excursions out of the visible area.

Try setting isolcpus=1

first captured picture show immediate after running, the next one is after waiting for 1~2 minutes

Those are terribly horrible results !
Was latency better before installing the DKMS drivers? Why and by who were you told to install DKMS?
If i recall correctly you had dropped link to Mesa board, but they were not from network issues, they were from huge latency issues, is this that topic?
Did you disable stuff in BIOS?
How much memory does the PC have?
