All, I have seen this panic twice today with the kernel sources being just a few days old. The kdb output is in the form of a screen shot which was the best I could do at the time ... http://hole.shrew.net/~mgrooms/files/tap-crash.jpg This occurred doing some tests with the following code. It just creates a tap device, configures it with an address/netmask/mtu and holds the file descriptor open until <enter> is pressed. I ran it in one terminal and started fiddling with ifconfig and netstat in another terminal. The panic happens eventually when the taptest program exits ... http://hole.shrew.net/~mgrooms/files/taptest.cpp Thanks, -Matthew
