This was present in my 2.2 as well, but was fixed in 2.3 (at least on
my 10 Mhz generic AT clone).  The CMOS is still a little more accurate
though, so I run a crontab to sync the UNIX clock with the CMOS time
once every 24 hours, in the middle of the night.

By the way, since Microport takes a lot of bashing in this group, I'd
like to mention that my System V/AT (version 2.3) has been up and running
for over two months continuously without a hiccup, as I'm writing this.
This system takes a partial newsfeed, polling UUNET a couple times a
day, and I access it extensively from remote locations since I'm
often away for weeks at a time.  The double panics went away completely
about 6 months ago when I replaced the serial card due to a lightning-
induced power surge taking it out, so I'm inclined to believe the panics
I was having previously were due to marginal serial hardware.  I'd
suggest that anyone still having serial-port-related double-panics do
some swapping of serial hardware...
