Mmmm, you might be right. I'm using a 3com 589, therefore I'm using
the ep driver.
Unfortunately I don't have a different PCMCIA network card at hand,
but I can try to reverse the crash test with my server. Yes, the
server is running exactly the same version (4.4-RC) but uses the de
driver.
So I did and, guess what, the find/cat test on my server over an NFS
mounted directory from my Vaio ran without a problem.
I've just done a further test. I've mounted a directory tree from
Vaio to Vaio using localhost (lo driver) and the test has run
smoothly. So chances would be good the bug is in the ep driver.
Unfortunately...

-rw-r--r-- 1 root wheel 2667 May 24 2000 if_epvar.h
none of the modules belonging to the ep driver has been touched for a
long time.
Side note. Regarding a different problem I've mentioned in
freebsd-hackers I've been told 4.4-RC has got problems with the PCCARD
code. Whether that can influence the ep driver is beyond my
knowledge.
