panic when entering S3 sleep state

["Pouya D. Tafti" <pouya%san-serriffe.org@localhost>]

Hi,

I previously had ukphy enabled in my kernel, which prevented my laptop
from entering sleep mode.  After disabling ukphy, when trying to enter
sleep mode using sysctl -w machdep.sleep_state=3, I now see


acpi0: entering state S3
Flushing disk caches: 13 done
uvm_fault(0xffff80004e6325e8, 0x0, 4) -> e
fatal page fault in supervisor mode
trap type 6 code 10 rip 0 cs 8 rflags 10246 cr2  0 cpl 6 rsp ffff80004e762928

This is with a current /amd64 kernel compiled from 23 Aug. sources.  I
don't know how to proceed in order to identify the source of the
problem.

Thanks,
Pouya

P.S. Is current-users the correct forum for such questions, or should
I post in port-amd64?
