I got the same panic tonight. The xlphy attach function doesn't clean up
appropriately when it aborts, here's the fix.

I am seeing exactly the same breakage -- cvsup as of today,
mid-evening EDT.  This is the first -current build I've
done since if_xl was converted to miibus.

My card is identified as <3Com 3c905B-TX Fast Etherlink XL>.

Best;

Sorry to reply to my own mail -- never report problems before
investigating what was committed.

The $Id$ -> $FreeBSD$ changes to ifconfig are probably not the cause --
more likely the changes to xl (1.52 -> 1.53), and the addition of the
mii-controller.  Anybody else seeing this, or should I look somewhere
else alltogether?
