Uncovered a couple of issues that may be impacting me....
Looks like this might be a kernel bug that was introduced in kernel 5.6.8, when USB4 support was introduced.
Unraid 6.8.3 which had kernel 4.19 did not have this issue.
The bug report post description accurately describes the issue "Batch mode top showing high CPU usage by usb_hub_wq and pm"
https://bugzilla.redhat.com/show_bug.cgi?id=1858291
Also looking at the output of dsmeg there are zenstates errors (I don't have zenstates added to go file)
Is zenstates part of the kernel or the unraid OS now?
