I've recently acquired a 3Com 3CSOHO100B-TX NIC, which seems to be supported
by the ``dc'' driver.  The output of pciconf is:

% none0@pci0:10:0:        class=0x020000 card=0x930010b7 chip=0x930010b7 rev=0x31 hdr=0x00
%     vendor   = '3COM Corp, Networking Division'
%     device   = '3C910 Integrated Fast Ethernet Controller (3CSOHO100B-TX Compatible)'
%     class    = network
%     subclass = ethernet

When I compile the ``dc'' driver into my kernel or load it as a module
though, a relatively recent CURRENT (updated yesterday, 14 Aug 2005)
panics after a port mapping failure.

The same panic happens when the device is configured into the kernel or
when I kldload if_dc.  Is anyone else using ``dc'' interfaces on CURRENT
and seeing similar problems?
