I tried running a D-link gig card on kernel 2.6.21.1
and it came up fine, but when I did a sftp of
an linux dvd ISO to it, the interface would lock
up hard with the error
eth1: hw csum failure.
Call Trace:

So I tried running the latest snapshot 2.6.23-rc3
and the almost the same thing happens. Only
difference is that now the entire box locks up.
The error is almost the same
eth1: hw csum failure.

I see that the new kernel includes some sort of
SKY2 DEBUG stuff. I would be happy to rerun
the test with that turned on, given some minor
direction.

Um, I thought 2.6.23rc WAS pretty recent. :-)
I'll check if there is something newer in the
repository now.

Okay, this is a fiber based card. Does the error happen right away (ie all packets
have bad sum), or is it sporadic (ie some magic packet or race in hardware).
Also are you using regular (1500) or jumbo (9000) mtu?
