Odd. I have exactly the same problem on both R10k and R12k Octanes, and
the Origin200... I just leave that port to "autonegotiate", and that
does the magic. If I somehow "force" the Catalyst into 100FDX, it's just
like you're saying.
Apparently, SGI has it's way of fixing this, just change a little line
in the kernel-files.
