If you run adjkerntz -a it fiddles the CMOS RTC clock and possibly the
"century" byte I think.  If your BIOS uses a checksum on the RTC and
adjkerntz doesn't know about it, your BIOS will think the contents is
trashed.

Try booting to single user and shut down immediately, does it still
happen then ?
