Hmm. At least I now know that it is not related to the Alpine, but also
happens on an EB64+, at least I assume you have an EB64+ It does annoy me..

Yes, that seems to help.

Something else: have you ever noticed abysmal performance using a 10mbit
DE Ethernet card? I get using ftp something like 250-300 kB/s, using 
NetBSD on the Alpine I get 800-900 kb/s (same server on the other side).
NFS (client) performance also stinks.

DE500 on 100mbit network does not seem to work at all. I will try that one
with NetBSD also.
