CONFIG_PCI_MSI as found in your configuration won't work, with any past or current pipeline release for powerpc (3.0.8 was certainly a fluke, or MSI was disabled there). The IRQ chip handlers are still attempting to mask the MSI source upon interrupt, which won't fly in the I-pipe case. -- Philippe.
