wvlan_cs and BIOS PnP problems?

I'm using kernel 2.3.99-pre9, pcmcia-cs-3.1.19, and wvlan_cs. Whenever I disable PnP in my BIOS (on a Sony Z505HS) the PCMCIA services lock up. However, I need PnP disabled to use the ALSA sound drive. I had compiled wavelan2_cs before with this same configuration, but I had to reinstall everything and now that won't compile due to an error that it's trying to "inline __mmdrop" in function mmdrop. A solution to either would be sufficient... Thanks, Matt

I didn't have PnP compiled into the pcmcia_cs drivers. Nor do I have it compiled in my kernel... Matt

Interrupt or IO port probe failure? Re: wvlan_cs and BIOS PnP problems? (Matthew GUthaus) Date: 2000, Aug 14 From: David Hinds <dhinds@pcmcia.sourceforge.org>

There are two possible reasons for lockups when PCMCIA starts up, with no cards inserted. It is probably either an interrupt probe failure, or an IO probe failure. The PCMCIA-HOWTO has instructions for how to tell them apart, and how to fix them. Disabling/enabling PnP support may change how your built-in devices are configured, which can change how these resource probes behave. -- Dave

Yes, limiting the IRQs with PCIC_OPTS="irq_list=3,5" fixed my problem. This was in the how-to, but I didn't read that far. :) Matt
