weird Ethernet problem with de21143

weird Ethernet problem with de21143

Post by Case » Mon, 15 Jun 1998 04:00:00



Hey,

I installed NetBSD 1.3.2 on my Micron XKE laptop with a docking station
with aic-7860 SCSI and de21143 ethernet behind a standard Intel mobile bridge
chip.

The first odd thing I noticed when booting was that the scsi controller and
ethernet controller were assigned the same irq. Could this be because
they're behind the same bride chip ?

After ifconfig and route commands I could see what was going on on the
ethernet but  was unable to ping anything, connect to anything, and
my machine was unreachable. Initially I just got arp requests, later ARP
was resolved, but still no connection.
Anyone have an idea what's going on ?
The 'abnormal interrupt' message would indicate that the irq assignment is the
root of the problems. However, there are no options for irq assignment
in the BIOS :(

Thanks.,
Casey

1. weird ethernet problem

we just got a e450 running solaris 7 from another dept where it ran ok
but now for some reason will not connect to the network using the hme0
interface. the cable, hub, files like hosts, hostname.le0, nodename,
netmask, defaultrouter, resolv.conf, nsswitch.conf etc are all ok. when
i try pinging another machine there is no response. tried checking the
interface at the openboot prompt with "watch-net" shows that the
interface is fine. it can ping itself and "ifconfig -a" shows it;s fine.
the netstat -rn shows the right enteries in the destination and gateway
coulmns but zeroes in flags, refcnt and use.

i even put in a sun quad fast ethernet card (drivers are there and the
system sees it, plus hostname.qfe0 and hosts file are proper) to see if
i could get on the network thru the qfe0 interface.same problem! one
thing that i did notice is that with the qfe0 interface the link green
light comes on whereas with the hme0 inteface it was off at the hub
connection. could it be that the hme0 interface on the motherboard is
partially impaired? what puzzles me is why there is no connectivity with
even qfe0.

running out of ideas...any suggestions most appreciated?

thanks in advance,
_bill
