None Asus P3B-F and Ricoh RL5C475 - mixed irq ?

I did a little more checking and I now believe that the problem is not
with the ThinkPad - it is with the router box on the other card. Maybe
rename this thread

The router box is a generic PIII machine, Asus p3b-f motherboard (6 pci
variant) and the pcmcia adapter is a Ricoh RL5C475 in slot 2 (slot 2 has
a dedicated irq).

When I boot the router (rh 6.2, pcmcia 3.1.13 with debug up at #3) I get
the following message:

card insertion gives me:

wvlan_cs: hcf_action(HCF_ACT_CARD_OUT) returned 0x0

my config.opts file is:

## begin
include port 0x100-0x4ff, port 0x1000-0x17ff
include memory 0xc0000-0xfffff
include memory 0xa0000000-0xa0ffffff, memory 0x60000000-0x60ffffff
include port 0xa00-0xaff
exclude irq 4
exclude irq 3
exclude irq 7
exclude irq 12
## end

I have no options for loading the i82365 module. When I cat out
/proc/interrupts, irq 9 is not in the list.

Perhaps the cause of the problems is the irq routing (00:04.2 -> irq 9
in boot message). What is this likely to be and how do I go about
disabling it - irq is not listed in /proc/interrupts (and not shown at
the post-bios pre-boot screen).

When I flip into windows 98 and setup the same network informatation
( I can ping between the cards - everything works - apart
from the choice of OS. Looking at the properties of the card gives me a
port range of 0x1000-0x103f, an irq of 9, and a memory slice of

Please let me know if I need to give more information to work this one

None Several PCI issues here

>     PCI irq 9 test failed

This is your problem.  The PCI interrupt test is unreliable for Ricoh
CardBus bridges.  This is fixed in the 3.1.15 PCMCIA drivers.  With
those drivers, you should be able to get the card to use the PCI irq
(irq 9).

Also, you will need to get the 6.01 beta version of Lucent's driver
for the Wavelan card, from in /pcmcia/contrib.  The
wvlan_cs driver does not work if the card is configured to use a PCI

Yay !

  Thank you David. Using 3.1.15 does work much better. I now have 11Mb
connectivity between the two cards.

  Both cards have taken pci irq 9. Your comment about the drivers
puzzles me - the cards seem to be behaving sensibly with the wvlan_cs
driver (1.04). I have the card firmware down at 4.52 (to stop wvlan_cs
choking on the tx threshold) - does the 6.01b driver requirement issue
relate to any firmware differences. I only ask because the cards seem to
be working great with what I believe are pci irqs. Am I likely to be
mistaking my irq types ?

Thanks again,

None Hmmm, I might be wrong about the wvlan_cs driver

The Lucent driver required a patch to work with PCI-to-CardBus card
readers and I thought I had a report of trouble with the wvlan_cs
driver in this configuration that went away with the new Lucent
driver.  But I haven't actually used either driver (and don't have any
Wavelan cards) so that information may have been incorrect.

If the cards seem to work fine, I wouldn't worry about it.  The older
Lucent driver would wedge the system at card configuration time, so
you would know it if you had the same issue.
