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: http://www.googlebit.com/freebsd/ (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?
