Hello, I just installed Ubuntu Server 10.04 LTS, running kernel 2.6.32-24-server, on a brand new Dell T110 server, supposedly fully compatible with Ubuntu Server.
I have two NICs: one ONBOARD, the other additional on PCI.
both of them are Broadcom netXtreme 5572.
on the first boot of the system, I could see both cards as eth0 and eth1 (with ifconfig)
I configured eth0 as static IP (as planned), and did not configure eth1.
after rebooting, one of the two NICs "disappeared": it does not appear in ifconfig at all.
the one that disappeared is the ONBOARD one. I investigated a bit and found the following things:
the card is SEEN, but not "installed", it appears as "UNCLAIMED" in lshw:

so I checked my dmesg and found a few strange lines, showing, there actually is a problem bringing up this card:
[ 3.737506] tg3: Could not obtain valid ethernet address, aborting.

that actually shows that one NIC is recognized, the other is not.
I researched a bit more, with lspci -v:

here I could see that the MAC address is 00-00-00-FE-FF-00-00-00, which, according to some forum posts on several websites, could be an issue.
I've researched everything I could on the net, and found out several people having slightly comparable issues, but they usually involve different HW, and do not provide a proper explanation / solution... I would appreciate if anyone around here has some info to share !
thanks
