FYI: After reading Jan Klemkow's response [0] to Mark's "Add acpipci(4) on amd64" mail [1], I recognized Jan's issue with resume after suspend. So I also disabled Thunderbold on my Thinkpad T480 (Bios -> Security -> I/O Port Access -> Thunderbold (TM) 3) and now my system is no longer slow when doing a cold boot.

Unfortunately the system remains slow (even when running for more than an hour) and CPU0 keeps at 85% sys. Furthermore, the CPU frequency scaling doesn't work so the CPU remains at 100% although hw.perfpolicy is set to auto. This also keeps the fans running at full speed and drains the battery rather quickly. Kind regards, Martijn Rijkeboer
Re: System very slow on cold boot
Not unexpectedly, lots of acpi interrupts when booted cold.
