Hello,

I tried the pata_pcmcia on 3(three) PC.but the result is same.
So I think the memory is good.

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.

Best Regards
Komuro
