I have a rackmount server that has a dual port onboard 82546EB card.

I've googled and seen this card apparently active with other users but
I seem to only get checksum errors.

The 82545GM card comes up fine but the 46EB card does not.

This is 2.6.20-gentoo-r6

I'll be happy to fulfill information request if needed.  Any
suggestions that'd help me get the 46EB working?


We haven't heard of any reports about this, can you get us some more
information about the platform this is in?
lspci -vv
dmesg (full version)
you can comment out the eeprom check and mac address check, rebuild
the driver and load it, then run
ethtool -e ethX
on the ports that are failing, without bringing the interface 'up'

you may have a hardware failure, or you could be having bus issues.
The eeprom read is the first point that we try to read a register from
the adapter so if register reads are failing this is the symptom you
will see.
