VirtualSMC/SMCProcessor KP #1504

Closed tarkh closed 3 years ago

tarkh commented 3 years ago

Hi guys! Today I caught KP on wake. It happens just once today, before everything was ok. So I thought maybe this information will be useful for developers. Thanks for amazing product) My sys. spec: CPU i7-3770K MacOS: Big Sur 11.2

KP log

Basically there is no obvious issue here, just a slightly abnormal delay during periodic job execution. I think the issue happened because you used a DEBUG build (try a RELEASE one) and because the CPU was in low power mode. I do wonder whether power management actually works correctly (i.e. MSR 0xE2 is unlocked and all the relevant tables are injected). If nothing helps, you can always disable SMCProcessor on this CPU.
