Got Page Fault Kernel Panic error Trap number 12. No time to take down the entire message as it rebooted after 15 secs. Thought it was due to hardware. Installed Freebsd 6.1 on another machine. Got same error. current process = 13 (swi4: clock sio) I think the machine started this Kernel Panic only after I added another NIC card and ran Ipfilter and in particular Ipnat. The message I got is probably identical to this: http://www.freebsd.org/cgi/query-pr.cgi?pr=91597 I applied the fix there on /usr/src/sys/contrib/ipfilter/netinet/ip_state.c ) I also applied the from http://www.freebsd.org/cgi/query-pr.cgi?pr=100098 on /usr/src/sys/contrib/ipfilter/netinet/ip_fil_freebsd.c But the problem still remains. I have the vmcore.# files (the system crashed many times) but no kernel.debug to use kgdb on them.
