PCMCIA and interrupts

Applicable to
S.u.S.E. version: all
Kernel version: all

Symptom:

The PCMCIA driver only assigns to the PCMCIA slots the interrupts 11 and 12. Since the built-in PS/2 mouse uses IRQ 12 as well, it cannot be addressed as long as two PCMCIA cards are installed.

Cause:

According to David Hinds, the PCMCIA package's developer, the i82365 driver's interrupt detection code does not work properly.

Solution:

Influence the driver's behaviour by setting the variable PCMCIA_PCIC_OPTS in the file /etc/rc.config to the following value:

PCMCIA_PCIC_OPTS="do_scan=0 irq_mask=0xefff"
