Question Dell I7500 with Xircom CBEM56G-100 - odd problem 

Forum: Xircom PCMCIA Ethernet Adapter Issues
Date: 2000, Feb 25
From: Jakob Frandsen jakobf

I watched this forum before posting this because I don't know
what else to do.

I'm using pcmcia-cs 3.1.11 and kernel 2.2.12-20 (RH 6.1)

After inserting the card, it beeps twice, logs no bad things,
ifconfig shows eth0 just fine, route shows the route just
fine, the light on the adapter does not come on showing "link
integrity". As soon as I try to ping somebody on my net, it
goes "Destination host unreachable" which is a weird error
considering that I route to the net. Running ifconfig after
this attempt shows that some "error packets" has been sent.

It's on IRQ 11 eventhough I have excluded that
in /etc/pcmcia/config.opts

I have tried to do the "ifdown eth0 ; ifup eth0" trick, but
that does not work for me.

Here are the details:

If you look at /proc/interrupts, do you see the counter go up when you
try to send packets?

"Destination host unreachable" isn't a routing error; it means that
the packets couldn't be delivered for some reason.

The card is being assigned to a PCI interrupt, which is why you can't
override it by fiddling with config.opts.  You could put:

    PCIC_OPTS="pci_int=0"

in /etc/sysconfig/pcmcia, to force the driver to use an ISA interrupt
instead.

Just checking: you're using a real network cable, right?  Not a piece
of phone cord?  I'm asking because I've had maybe five bug reports in
the past two weeks, that turned out to be from people using old phone
cords or home-made cables.

Ok It works now - stupid faulty cable. :(

I learned a lesson: never assume a new cable fresh from an unopened plasticbag actually works! :)

Anyway, it works now, with another cable. Thank you very much for your assistance though.
