I have no problems with my card and the fxp driver in NetBSD 1.6.1
(with cvs stable updates).  I grepped through my logs just to be sure and
found nothing.

I'm running:
fxp0 at pci2 dev 9 function 0: i82559 Ethernet, rev 8
fxp0: interrupting at irq 11
fxp0: Ethernet address 00:02:b3:99:69:b2
inphy0 at fxp0 phy 1: i82555 10/100 media interface, rev. 4
inphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

I'm using a stock Dell with a:
cpu0: Intel Pentium 4 (686-class)...

I've used this card in NetBSD 1.6.1 for several months without problems.

ifconfig -a reports:
        address: 00:02:b3:99:69:b2
        media: Ethernet autoselect (100baseTX full-duplex)

If there is anything I could help test let me know.
