FYI, I just checked in a fix. Please update dev/acpi/acpi.c and arch/x86/acpi/acpi_wakeup.c and try again.
That fix is sadly not correct as mtrr_commit requires IPIs.
How early do we need to restore mtrrs? I'd rather that be part of the cpu pmf handler if possible.

I think as soon as possible. Anyway, I suspect some of the wake events

There were some bug fixes related to this in ACPICA, but it's too late for us to pull in a new version for 5.0
