Well, we're getting somewhere but not really there yet.  Somehow IRQ 
routing didn't get setup right.  I don't have much idea on how to track 
it down.  Cc'ing linux-pci and linux-pcmcia.

Hello, guys, on tp60, IRQ on PCMCIA CF controller isn't working.  I 
don't know whether this is because IRQ isn't routed properly or someone 
didn't wire the ATA interrupt line.  Any ideas?

Thanks.
