Just to confirm, I have this exact problem as well. This is my hardware:

wm0 at pci2 dev 0 function 0: Intel i82573E IAMT, rev. 3
wm0: interrupting at ioapic0 pin 16 (irq 11)
wm0: PCI-Express bus
wm0: FLASH
wm0: Ethernet address 00:16:76:be:71:6c
makphy0 at wm0 phy 1: Marvell 88E1111 Gigabit PHY, rev. 2
makphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FD
X, auto

It happens rarely, but I have also gotten panics when, IIRC, wm is
changing media (during boot only, never after post-init).  This hasn't
negatively affected me too much, as I only have my small personal
network with a cable modem, but of course I'd like to see it fixed and
will help in any way I can toward that end.  Does anyone have any
insight into what's happening here?  AFAIK, this is a well-known,
long-standing problem.
