NASLite Network Attached Storage

NASLite+ and FDU 1.4
Intel Pro/1000 MT

Boot up, get GB link light. Network is detected and initialized by NASLite.
-- No connectivity... Everything on the PC looks good, but machine can't be pinged. After a minute or so, I get:

NETDEV WATCHDOG: eth0 transmit timed out

I can leave all the setting the same, throw in a 100mb card and it works perfectly.

I saw another thread with this same error, but was of no help.

I also threw in a Netgear 311a (realtek 8169) and it get a totally different error. I don't think the Netgear card is compatible.

Any ideas?

There are some 1000 network cards that work fine, a list is in the forum about hardware.

I use a netgear FA311 and it works fine.
