Ok so we got an interrupt this time and then when we asked for it got
told "no". That still shouldn't crash but there are some lurking
problems when ata_device_add fails.

More interesting is how it can occur.

We asked for an IRQ that was "exclusive". We got given IRQ 11 which was
shared. A look at the pcmcia code suggests the new drivers/pcmcia code
is broken here: It may fall back to using an interrupt line that is
shared even when told not to.

What occurs if you change

ae.irq_flags = 0;


ae.irq_flags = SA_SHIRQ ?
