There's a problem with IRQ0 with respect to mini-PCI-E slot. I have
Atheros wireless card plugged
into it. ath9k wireless driver for this card uses legacy PCI-E
interrupts, and I get "irq 16: nobody cared"
message when driver executes request_irq(). Vivek has come to a
conclusion that the problem is
related to incorrect IRQ0 routing for mini-PCI-E slot on P2020RDB.
Felix.
