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.
