Jack, i have played with kernel settings all day today trying to
repoduce  the bug and recompiled kernel probably 20 times ;)

This is all totally weird, i went to back 4BSD scheduler,
set polliing option in kernel, set HZ=1000, so, effectivelly
i went back to the setup where i had this problem BUT the 
problem never appeared again. I did not do any cvsup since then, so,
it is all the same source. But now everythig work flawlessly with TSO4
option on interface. 

I am really sorry to waste your and other peoples'
time, but beleave me, the problem was really persistent and it was there
for more than a month.

I think you are right and it was some kind of speed mismatch with
the cisco router or some kind of electrical problems, either way it
went away and now everything works.
