I need some help determining why a machine is panicing. Specifically,
whether it's FreeBSD or the hardware that's causing it. I really want to
bring in FreeBSD as the OS of choice to provide our core services, but
this is really hurting my cause.
When I first installed 3.1 on the machine (an Apricot Shogun), I left
the box in a continuous loop doing "make world" for a couple of days. No
problem. I assumed the hardware was good. It'd also been previously
running NT 3.51 for well over 2 years. However, now it's running inn-2.2
(CNFS with mmapped files), the box keeps panicing (every day or so), with
a page fault. It always does this at exactly the same place in the kernel.
The gdb -k output is:
