Description of Problem: Default setup fails to recognise the Plug-and-Play ISA-to-PCMCIA brigde I have (Linksys PCMRDWR). How Reproducible: Always Steps to Reproduce: 1. Install Linksys PCMRDWR hardware 2. Set PCMCIA=yes PCIC=i82365 in /etc/sysconfig/pcmcia 3. Reboot the machine. Actual Results: /proc/isapnp would show the device as inactive and pcmcia would log: Linux PCMCIA Card Services 3.1.22 options: [pci] [cardbus] [pm] Intel PCIC probe: not found. Expected Results: Pcmcia would recognize that device is present and activate and use it. Additional Information: If I activate the device using isapnp, then pcmcia starts and works fine. Of course, rc.sysconfig would not start isapnp because /proc/isapnp is present, so I ended up a) Disabling the /proc/isapnp check in rc.sysconfig, so that isapnp would be ran even when it is present b) Putting only the Linksys card config into /etc/isapnp.conf and letting rc.sysconfig deal with the sound card (which works fine even without running isapnp).

What does your /proc/isapnp look like? In theory, we could add isapnp support to the i82365 driver.
Created attachment 18570 [details] /proc/isapnp (after all devices are activated)
Created attachment 18571 [details] isapnp.conf - notice that I only have to deal with PCMCIA hardware, the sound hardware is taken care of by the kernel.
Yes, I agree that the best long-term solution is to have PNP support in the appropriate driver.
I no longer see this problem in Roswell2 (RC1) - it seems that in 2.4.7-2 the PCMCIA modules are capable of doing isapnp properly without any need for user-space isapnp tool.
