So your AP (Application Processor) seems to get fault, most likely in the
trap handler. There were absolutely no changes in the stable/11 in the
area of SMP startup for quite long time.
To get anywhere, you should perhaps add ddb to your kernel configuration
and get the backtrace. The backtrace would be long, I am only interested
in the first several frames before faults go into recursion.
But, since 1 month earlier kernel worked, and there were no changes, this
might indicate either a failing hardware (your machine is quite old, it
is Core2 Xeon, am I right ?) or problems with your build environment.
