Sad: Wavelen(Lucent) PCI-PCMCIA adapter problems 

Forum: PCMCIA Installation and Configuration Issues
Date: 2000, Jul 27
From: Stuart Butterfield ButterfieldS 

I'm having problems trying to remotely configure wireless
networking for a colleague in Eindhoven! He's got a Lucent
Wavelan Turbo 11mb card and one of their PCI-PCMCIA 
adapters.

I have the same equipment working on a PC on my desk,
but cannot get it going on his machine. I've tried the
latest PCMCIA sources (3.1.19) and the ones that are 
working for me (3.1.14), with the same result:

kernel: Linux PCMCIA Card Services 3.1.14 
kernel:   options:  [pci] [cardbus] [apm] 
kernel: PCI routing table version 1.0 at 0xf6740 
kernel:   unknown PCI interrupt router 8086:2420 

I've seen a few other folks post messages with similar
problems, but I'm not sure if the previous suggested
causes apply here.

The device in question shows up in /proc/pci

  Bus  0, device  31, function  0:
    ISA bridge: Intel Unknown device (rev 1).
      Vendor id=8086. Device id=2420.
      Medium devsel. Fast back-to-back capable.
      Master Capable.  No bursts.

and from lspci

00:1f.0 ISA bridge: Intel Corporation 82801AB 82810 Chipset
        ISA Bridge (LPC) (rev 01)


Any advice greatly appreciated.

Unknown interrupt router

Try the 27-Jul-00 beta on projects.sourceforge.net in
/pub/pcmcia-cs/NEW.  That should fix at least this part.

Thanks for that David, you are correct in that it has fixed 'at least
this part'. Any idea now how to gert it to see the controller?
Starting Card Services gives the following messages:

# /etc/rc.d/init.d/pcmcia restart
Shutting down PCMCIA services:.
Starting PCMCIA services:

    /lib/modules/2.2.14-5.0/pcmcia/ds.o:
       init_module: Device or resource busy cardmgr.

And in /var/log/messages:

I suppose there's always a chance my colleague hasn't actually
inserted the PCI-PCMCIA cards correctly ... :-(

That is not a good sign

Oof, that is bad.  I've had a few reports of systems that refuse to
notice that these PCI cards even exist.  Check to see if the card
shows up in /proc/pci or "lspci".  If the linux PCI system does not
see the card, then there's no way for the PCMCIA drivers to do
anything about it.

If this is the case, try contacting Martin Mares, mj@ucw.cz.  He is
the Linux PCI maintainer.

Agree: Yep, it's a PCI failure

David, you're assumption was correct. There's no sign of the Lucent bridge in /proc/pci or lspci. I'll take it to the PCI guy.

Many thanks for your help.

Note: Got another PCI adaptor working

From: Brian Candler <b.candler@pobox.com>

I recently bought a 'Melco/Buffalo' card, which appears to be a rebadged WaveLan Silver. It came with its own PCI adaptor card, which the kernel identifies as a Ricoh RL5c475.

With older versions of pcmcia-cs I could not get the interrupt handling to work (i.e. it would send one packet and then time out). With 3.1.19 it now works fine if I use 

 PCIC_OPTS="irq_mode=0 pci_irq_list=11"

Thanks David!! The reason I had to manually give the PCI interrupt appears to be a bug in the kernel PCI code, because I think it is in the configuration table. See below.

Regards,

Brian.
