FWIW, I just tested a current git kernel (v2.6.33-rc2-268-g45d28b0) with Tejun's patch applied on my N130. The ATA exception and hang is indeed gone, just "ata1: clearing spurious IRQ" is logged.
I've see Tejun's comment in http://bugzilla.kernel.org/show_bug.cgi?id=14314 and I would like to add that the ATA irq is not shared.
14: 43885 0 IO-APIC-edge ata_piix 15: 0 0 IO-APIC-edge ata_piix
Thanks, Johannes
