Does putting msleep(100) in the > pata_pcmcia init_one make any difference? I tried the msleep , but it still does not work. By the way, If I delete the pata_pcmcia.ko from /lib/modules/... and insert the ata pcmcia card, only /sys/bus/pcmcia/devices/0.0 exist. But if I install the pata_pcmcia.ko, /sys/bus/pcmcia/devices/0.0 and /sys/bus/pcmcia/devices/0.1 exist. Maybe the sysfs or something like that is the problem.
