Kernel Panic 12 since 4.8

[Ben Pfountz]

I have been getting the same panic.  I haven't been able to narrow down the
source of the panic.  Have you tried the debuging kernel?
(http://www.onlamp.com/pub/a/bsd/2002/03/21/Big_Scary_Daemons.html) I have
set it up but unfortunatly my swap partition is smaller than my physical
memory.  I will fix that when I get home and wait for a panic.

Just curious, are you using IPFW2?

Ben
