Thanks for testing!

It seems that the message will show up in case of firmware loading/ring
initialization failure. Try attached patch which will show failing
function name.

Because I don't have 3CR990 hardware it's very hard to fix it. I'm unsure
remote debugging would help here.
Btw, it seems the hardware looks very good(except for extra copying on
strict alignment architecture) and it even supports TSO!
