Sad Wavelen(Lucent) PCI-PCMCIA adapter problems 

Forum: PCMCIA Installation and Configuration Issues

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.

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

Note Got another PCI adaptor working

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.
