Instant reboot on new interface coming up

I've been having issues lately when trying to bring up a new interface.
It's a hard problem to actually see, because it makes my machine
instantly reboot.
Here's what I see:
Normally, I use ath0 for wireless, and occasionally I use em0.
Recently, when I was at a location with no wireless and no dhcp support,
I powered up my laptop, plugged in to em0, and did an ifconfig em0 xxx.
After a few seconds, the system spontaneously reboots. I figured
out that killing dhclient on that interface before attempting to
manually configure it helped.
Now, I also tried to connect using ppp to a GPRS network (via bluetooth
through my cell phone). This used to work just fine, probably a few
months ago. This time, I killed all dhclients, connected the bluetooth
pieces, and then ran rfcomm_pppd, which creates a tun0 interface. When
the interface was created, and brought up without dhclient, everything
worked ok. When I accidentally left dhclient running, and tun0 was
created, when the device got it's IP address, machine rebooted.
I have various machine logs/dmesg/etc here:

(labeled by date - look for the most current versions)
I'm running 7.0-CURRENT as of a few days ago.
I have all the debugging, WITNESS, and other flags set.
Any ideas?
