Description Aleksey Nogin 2001-05-14 13:56:22 UTC 
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).

See also bug #35111 for another discussion of PNP issues in RedHat 7.1
Comment 2 Bill Nottingham 2001-05-16 02:06:17 UTC 
What does your /proc/isapnp look like?

In theory, we could add isapnp support to the i82365 driver.

Comment 5 Aleksey Nogin 2001-05-16 05:18:10 UTC 
Yes, I agree that the best long-term solution is to have PNP support in the
appropriate driver.
Comment 6 Aleksey Nogin 2001-08-21 15:29:47 UTC 
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.
