This looks a lot like an IRQ problem. Look for available IRQs by
grepping dmesg for the string "irq" and from vmstat -i. There will be
VERY few available. Eliminate 2 and 13 which, I am told by people more
expert than I, are never available. Then edit /etc/pccard.confg to
start with the line:
irq 3 8 9 (or whatever you think is available.)
You might be able to free up IRQs by eliminating devices your don't
need (like extra serial ports or an unused parallel port). The most
likely are 8, 9, and 10. If you turn off the parallel port, that
should free up 7. Sound cards on laptops may be in a LOT of different
places. Mine is at 5. If your pcic is using an IRQ, it probably uses
10.
Good luck,
