possible bug in pd6729

[Komuro]

Hi,

>[   50.688869] pd6729: Cirrus PD6729 PCI to PCMCIA Bridge at 0x0 on irq 0
>[   50.693063] pd6729: ISA irqs = 3,5,7,9,10,11  polling status changes.

The io_base of pd6729 in your docking station is 0,
so this is PCI setup problem.

Please try the following patch.

Best Regards
Komuro
