The line you refer to here is line 4236. So, I shall have to attempt the upgrade again, and verify that all modules loaded were built under 9.2. I believe only pefs.ko is one I built myself, and all others came with the system... and freebsd-update would have updated those modules (in /etc/freebsd-update.conf I have "Components src world kernel".

When I have a time where I can attempt the update again, I will reply with my findings.

Thank you for your help,
Matt
