>Description:

        I transfered some MB and suddenly I got the following panic (hand 
written):

trap type 6 code 2 eip c0611ed4 cs 8 eflags 10286 cr2 ba851408 ilevel 7
kernel: supervisor trap page fault, code=0

        There is no support for the phy in 5.0_STABLE.
        That was only recently added in current (2009/12/13 and 2009/12/14):
                src/sys/dev/mii/makphy.c        rev 1.33
                src/sys/dev/mii/miidevs rev 1.91

>How-To-Repeat:
        I'm not sure, but in my case I transfered some MB before it happend.
