Red Hat Bugzilla – Bug 40551
Default setup is not working with PNP ISA-PCMCIA bridge
Last modified: 2007-04-18 12:33:13 EDT
Description of Problem:
Default setup fails to recognise the Plug-and-Play ISA-to-PCMCIA brigde I
have (Linksys PCMRDWR).
Steps to Reproduce:
1. Install Linksys PCMRDWR hardware
3. Reboot the machine.
/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.
Pcmcia would recognize that device is present and activate and use it.
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

What does your /proc/isapnp look like?
In theory, we could add isapnp support to the i82365 driver.

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
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
