macdep.sleep_state=3 panic on T500

[David Brownlee <abs%absd.org@localhost>]

Tried to put my T500 to sleep (amd64, GENERIC 5.99.39 kernel from 24th
oct) and it panics.

Testing booting -s and:

# sysctl -w macdep.sleep_state=3
acpi0: entering state S3
Flushing disk caches: done
uvm_fault(0xffff800047cf5b80, 0x0, 4) -> e

NetBSD forsaken 5.99.39 NetBSD 5.99.39 (GENERIC) #0: Sun Oct 24 amd64


anyone have any thoughts as to what I might look at?

thanks
