PCMCIA: Keyboard doesn't respond anymore

Symptom:

You installed PCMCIA support to your laptop and activated. Booting seems ok, but your cannot login. Neither the keyboard nor the mouse are responding.

This error can occur during installation, too, if using PCMCIA modules.

Cause:

From PCMCIA-Howto:
After identifying the host controller type, the socket driver probes for free interrupts. The probe involves programming the controller for each apparently free interrupt, then generating a ``soft'' interrupt, to see if the interrupt can be detected correctly. In some cases, probing a particular interrupt can interfere with another system device.
In this particular case it interferes with IRQ 12 of the PS/2 controller.

Solution:

From PCMCIA-Howto:
The interrupt probe can be restricted to a list of interrupts using the irq_list parameter for the socket drivers. For example, ``irq_list=5,9,10'' would limit the scan to three interrupts. All PCMCIA devices will be restricted to using these interrupts (assuming they pass the probe). You may need to use trial and error to find out which interrupts can be safely probed.
The probe options can be specified using the PCMCIA_PCIC_OPTS definition in /etc/rc.config, for example:
PCMCIA_PCIC_OPTS="irq_list=3,5,7,9,10"
If you have this error during installation, you can use this option at the second prompt, when loading the PCMCIA modules. Enter irq_list=3,5,7,9,10 when you are asked for specific parameters for chipset "i82365".
