Subject: NetXen NX3031 failing test, reporting link down, not working

Hi,

I have HP DL 120 G6 with two Quad-GE Cards based on NetXen NX3031 (rev
42) [4040:0100]. The boxes are running with a grml daily image with
kernel 2.6.36.1 for the time being, and the NetXens are giving me a
hard time.

This is the dmesg for two of the eight Interfaces (for brevity).

They work fine when I have two NetXens connected back-to-back (at
least I can ping the other side), but they do not work when one of the
NetXen Interfaces is connected to an HP ProCurve 2848.

The switch happily says the link is up, while ethtool says "Speed:
1000Mb/s, Duplex: Full, Link detected: no", and ethtool -t offline and
ethtool -t online both say "The test result is FAIL".

Do the netxens need Firmware to work and do not complain when the
firmware is not found? Any ideas how do debug this?

I am not sure whether this is appropriate for netdev@...r. If so,
please tell me and I'll re-send there. I'd appreciate any pointers to
any resources about the NetXen interfaces.

Greetings
Marc
