Hallo,

I have here Tyan GT20 (B2865G20S4H) barebone server with onboard GbE NICs
(Broadcom BCM5721 and Marvell 88E1111-CAA PHY).

I have installed PCI-E Intel® PRO/1000 PT Quad Port Server Adapter
(EXPI9404PTBLK) to gain 6 ports altogether. This is the card:

http://www.intel.com/products/server/adapters/pro1000pt-quadport/pro1000pt-quadport-overview.htm

Now, with Debian 5.0 Lenny (distributional kernel 2.6.26), only the onboard
cards are functional. The Intel is also recognised by the kernel, is assigned
ports (eth2-5), however none of them works when connected to network. The NIC
is aware of plugging or un-plugging the cable (displays message on console),
however no communication is ever performed, and the connected port just lazily
blinks.

After some rochades hard to reproduce (plugging, unplugging, configuring
interfaces, resetting etc), it even worked for few seconds, and then died out
again forever.

I have also compiled fresh 2.6.30 kernel, no advance however. Interesting, that
ifconfig always revails huge number of errors for the port.
