#19540 new defect
CPU overcranks on Macbook Air i5 early 2020 after sleep (either guest OS or host)

Description
Debian and Ubuntu guests operate normally until after waking from sleep -- either suspending the guest while leaving the OS awake, or sleeping the host OS with the guest either awake or asleep. After waking from any of those states, the CPU maxes out to the thermal limit and stays there until the guest is halted, after which CPU behavior reverts to normal and temperatures stabilize at normal levels (40-55 C depending on other operations). This happens even when all other applications are off. Since it includes both guest and host, this may be two separate problems. Occasionally it does not happen with guest suspend, but it is 100% with the host os sleep. This does not happen on my 2018 Mac Mini, so as far as I know it's specific to the new Macbook Air.
This double-entered for some reason, probably my bad. Is there a way to delete this ticket?
