Hello,

Latest git, insert a CF card into cardbus slot gives:

pccard: PCMCIA card inserted into slot 0

Disabling IRQ #9

ata3.00: qc timeout (cmd 0x91)
ata3.00: failed to IDENTIFY (INIT_DEV_PARAMS failed, err_mask=0x4)

However, if I rename pata_pcmcia.ko so that udev cannot autoload it, insert the
card and manually load pata_pcmcia.ko it works:

pccard: PCMCIA card inserted into slot 0
