I've just built a new kernel on my SMP -STABLE machine, and I get a
repeated panic on running ifconfig. Here's a backtrace:

From the dmesg (all available if you need it):
dc0: <Macronix 98715AEC-C 10/100BaseTX> port 0xc400-0xc4ff mem 0xeb000000-0xeb0000ff irq 3 at device 9.0 on pci0

I can't get a dump for some reason (well, it dumps, but when I reboot
the system claims there isn't one). I can repeat the problem,
however.
