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.

The system is absolutely idle. As other people reported in between, issuing on this
Samsung Laptop
echo disable > /sys/firmware/acpi/interrupts/gpe13
the high kworker load disappears. But I find it scary to do this without knowing what
effect this has on the system.
