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".
