I just sent this off to freebsd-bugs - I too had the kernel panic, but a
slightly different scenario. I'll try that patch to see if it helps my
situation as well. Read on if you're interested...

Hi...

I experienced a very similar error after cvsup'ing on 8/9/02. However, my
message was slightly different and might not be related:

Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x0
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc016e580
stack pointer = 0x10:0xcdb17d08
frame pointer = 0x10:0xcdb17d10
code sgement = base 0x0, limit 0xfffff, type 0x1b
 		DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 85 (sendmail)
interrupt mask = net tty
trap number = 12
panic: page fault

Now... here's the odd thing; I'm not running sendmail. My /etc/rc.conf
looks like this:

linux_enable="YES"
sshd_enable="YES"
pccard_enable="YES"
ifconfig_ep0="DHCP"
hostname="bjohnson.mydomain.com"
pccard_ifconfig="DHCP"
sendmail_enable="NONE"
portmap_enable="NO"
firewall_enable="YES"
firewall_type="open"

So I'm not sure how sendmail is even starting. But this is where it gets
even more bizarre. If I comment out the firewall_enable and firewall_type
lines, the system boots fine. 

And yes, I have option IPFIREWALL in my kernel conf.

Something this random could easily be a memory-related error, I guess.
Might Max and I have similar problems?

Again, I'm on the 4.6 STABLE branch and just cvsup'ed today.

Thanks,
Brad Johnson
