>Description:
	While installing a new machine, I found that I could not get the
	network card to respond properly using the default settings.  After
	experimenting with the media settings, I found that the card would
	only talk properly using 10baseT/half-duplex - setting full-duplex
	or 100baseTX (or both) would cause it to fail with a 'device timeout'.

	Watching the other end of the link, the link signal would show up
	at the (forced) speed and duplex until I tried to do anything with
	the network (e.g. ping another host).  Then, the link signal would
	go down for a few seconds, and then the machine would return
	'fxp0: device timeout'.

	I tried both the stock 1.4 INSTALL kernel and a modified version.

	Booting a 1.3.3 INSTALL kernel, though the card only autonegotiated
	10baseT/HDX, I was able to set both ends to 100baseTX/FDX and
	the network Just Worked.

	(In case it's relevant, the device on the other end of the link
	is a Cabletron SmartSwitch 6000, and I tried ports on both the
	6H122-08 and 6H202-24 (10/100 UTP) and 6E132-25 (10 UTP) modules.)
	
	dmesg follows (failing 1.4 first, then working 1.3.3):
