This is in cases when you expect the system to be idle? i.e. no disk access, no
active processes running, or network activity? Or is there something going on, like a file
copy, but you just don't expect kworker to be consuming 80%? If the latter, I have a
similar case with two (U)EFI laptops; I haven't narrowed it down to network access or
disk access. But if neither are occurring, then I do get idle and no kworker process CPU %
is significant.
