This driver doesn't work with FC6, kernel 2.6.20+

The driver loads:

NTCARD Device Driver Ver 7.1.0
Copyright (C) 2004-2012 Rayon Company, Ltd.
All Rights Reserved

PCI: setting IRQ 10 as level-triggered
PCI: Found IRQ 10 for device 0000:00:0b.0
.....Device1=P640N Jp=1 box=3 port=24 IRQ=a

Then any attempt to access any of the ports (setserial, minicom etc) kills the module:

The module is then frozen and you must unload and reload it.

Please make it work !
