First time I've seen someone saying this about a NIC that isn't 3com !
Hmm, I've been experiencing this sort of behaviour for some time (since
960323-SNAP) on my laptop using a 3c589c. I'm now on 960801 on my laptop,
and am still experiencing it:
anorak $ cat /usr/local/bin/keepalive
#! /bin/sh
test $# -ne 1 && { echo Missing IP >&2; exit; }
while :; do ifconfig ep0 inet $1; sleep 5; done &
I assumed that this was a PCMCIA thing, but I recently installed 961006
(and scontrib from 961014) on a P75 w/ a 3com ISA card - not sure what
it is, but is uses the ed driver. The NIC has "hung" three times in the
last week (light load) - unfortunately, I hadn't time to muck around and
experiment.
The *really* interesting thing is that my laptop didn't lose it's
connection to the P75 (at least once) !
I'm not ruling out a tcp_extensions (see /etc/sysconfig) problem, although
this certainly *wasn't* the problem with my laptop running 960323.
Having said all that, I've never seen the problem on my other two machines
that run FreeBSD - one has an SMC ISA card using the ed driver and the
other has an SMC PCI card using the de driver, and my laptop's 3com NIC has
died while talking to these machines.
My current "opinion" is still that 3com sucks :( Maybe IBM sucks too :O
