Hello, sorry about the late reply, I was on vacation.
Hmmm... This is the first time I see ata_piix taking down interrupts which
aren't assigned to it. I wonder what happens if uhci and ehci are loaded first
and then ata_piix is loaded. I couldn't find any option to easily achieve that
in the current. cc'ing Thomas for the possible IRQ routing issue. Thomas,
loading uhci, ehci and ata_piix cause nobody cared on IRQ take IRQ 16 and 18
down by causing IRQ storm. The ata_piix controller is assigned IRQ 18, so I'm
a bit skeptical about the role of ata_piix but we never know. Does anything
ring a bell?
Thanks.
