I installed FreeBSD 4.0 onto a i486DX that has an Intel EtherExpress
Pro NIC, ex0. The NIC has been acting weird with 4.0 where there
previously were no problems with 3.x.
After I boot up, if I try to connect to or ping the 486 from others on
the LAN, there is no response, just,
sendto: Host is down
Messages. Likewise, if I go to the console of the 486 and try to ping
out, nothing. tcpdump(8) on one of the other machines shows silence
from the 486. However, this is where it gets strange...
The 486 has,
ex0: flags=843<UP,BROADCAST,RUNNING,SIMPLEX> mtu 1500
inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255
ether 00:aa:00:a5:af:91
from ifconfig(8) and,
ex0: <Intel Pro/10> at port 0x300-0x30f irq 10 on isa0
ex0: Ethernet address 00:aa:00:a5:af:91
From dmesg(8), but like I said, networking does not work. I start a
ping on one virtual console and get,
sendto: Host is down
sendto: Host is down
sendto: Host is down
On and on. Then, I go to another console and try turning on tcpdump. I
get,
ex0: promiscuous mode enabled
A few seconds of silence and then, "Boom!" ping packets are flying. If
I go back to the ttyv where I was pinging, suddenly things are
alive. When I turn off tcpdump, thing continue to work fine after we
switch back out of promiscuous mode.
It seems like the network card is not being properly initialized by
the system. I have tried re-ifconfiging it, but the tcpdump seems the
only thing that wakes it up that I have found.
Has anyone seen this? Anyone have a solution? Anyone have suggestions
for documenting it so it can be debugged and fixed?
Thanks.
