>Description:
We are trying to upgrade our web server to 5.3-RELEASE 
but as soon as we put it into service, kernel panics/reboots start.
We had 5.3-RELEASE on our identical hardware (SuperMicro SuperServer
6013P-8) running as our mail server and had the same behaviour, so
we quickly reverted back to 4.11-RELEASE and the kernel panics
stopped. Kris Kennaway suggested upgrading the kernel as per the
FreeBSD-EN-05:03.ipi Errata Notice which shows no improvement. We
are using the generic kernel with the SMP option.
