So we're still unhappy, but something did actually change. I wonder why ACPI matters. It must be changing the polarity or trigger of the irq somehow - but your earlier dmesg output seems to imply that it only changes ELCR for irq9, so it must be somewhere else. Len, ideas? Also, Marco, it might actually be a VIA IDE driver bug, that leaves the interrupt on during setup somewhere (and the bug just doesn't matter when the IRQ is edge-triggered). So it would be interesting to know what happens if you disable the VIA-specific IDE support... (Btw, thanks for being so good at testing, despite the lack of major progress).
