I don't know what MFCes were done, at least I didn't MFC any

I'm not sure what is root cause of this panic. If you can reliably
reproduce the panic would you let me know?
CURRENT has a couple of fixes for edge-cases as well as some new
hardware features(TSO, VLAN hardware tagging and WOL etc). Would
you try latest fxp(4) in HEAD?
I think you can use cvsweb interface to get latest files.

Hi Pyun
The system reliably panics on boot up. I tested fxp from HEAD with the
same result.
7.1-RELEASE = Panic
7.1-RELEASE with fxp from HEAD = Panic
7.1-PRERELEASE from Tue Nov 25 = operates as expected
This is an old card. Some details on the card:
fxp0: <Intel 82559 Pro/100 Ethernet> port 0xd100-0xd13f mem
0xfca03000-0xfca03fff,0xfc800000-0xfc8fffff irq 17 at device 9.0 on pci0
miibus0: <MII bus> on fxp0
inphy0: <i82555 10/100 media interface> PHY 1 on miibus0
inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto
fxp0: Ethernet address: 00:d0:b7:6c:1c:0a
fxp0: [ITHREAD]
f...@pci0:0:9:0: class=0x020000 card=0x000b8086 chip=0x12298086 rev=0x08
hdr=0x00
vendor = 'Intel Corporation'
device = '82550/1/7/8/9 EtherExpress PRO/100(B) Ethernet Adapter'
class = network
subclass = ethernet
As a test, I unplugged the ethernet cable and the system booted fully,
however it produced a panic as soon as I connected the cable. This
backtrace is from 7.1-RELEASE with fxp sources from HEAD.
