Hi,

[foner: I included you in the CC because your problem seems similar.]

Well, you reached the right person.

This is interesting. Does the problem persist if you ifdown the interface?

That is even more interesting. So the bug affects forcedeth, but not
nvnet. Hmmm. We'll have to review the code again.

Foner: Do you see similarities between your problem and this one?

Janusz, Foner: Are you willing to test forcedeth with a few dozen
iterations of
patch, recompile, install, power down, power up and test again?

I would send you patches to binary search the offending code.
