    We'll have to try harder. -mm2 is up there now, to break everything again.

    I'd be suspecting the PCI changes firstly. That's gregkh-pci-*.

    Conceivably git-acpi, but that hasn't changed in quite some time. In fact,
    no ACPI changes since 2.6.14-rc5-mm1.

    After that I don't know, sorry. Binary search time?
