There's a bug in the ata driver that Ian Downes has a patch for.
Since cardbus bridges are now using level interrupts to allow sharing
(which is why it used irq 9, the same as your bridge), cards that
assert interrupt, but don't clear it, will cause the machine to hang
in an interrupt storm.  Ian's patches fix that.
