    This patch breaks my x366 machine:

    aic94xx: device 0000:01:02.0: SAS addr 5005076a0112df00, PCBA SN , 8 phys, 8 enabled phys, flash present, BIOS build 1323
    aic94xx: couldn't get irq 25 for 0000:01:02.0
    ACPI: PCI interrupt for device 0000:01:02.0 disabled
    aic94xx: probe of 0000:01:02.0 failed with error -38

    Reverting it allows it to boot again. Since the patch is "obviously
    correct", it must be uncovering some other problem with the genirq
    code.

    Cheers,
    Muli
