Hi,
Your patch db8be50c4307dac2b37305fc59c8dc0f978d09ea is causing my ia64 Altix system to die with an MCE in early boot.
Good dmesg looks like this: ACPI: PCI Root Bridge [P001] (0001:00) pci 0001:00:01.0: reg 10 io port: [0x1000-0x10ff] pci 0001:00:01.0: reg 14 64bit mmio: [0x700000-0x703fff] pci 0001:00:01.0: reg 1c 64bit mmio: [0x710000-0x71ffff] pci 0001:00:01.0: reg 30 32bit mmio pref: [0x800000-0x8fffff] pci 0001:00:01.0: supports D1 D2 pci 0001:00:02.0: reg 10 64bit mmio: [0x720000-0x72ffff] pci 0001:00:02.0: PME# supported from D3hot pci 0001:00:02.0: PME# disabled pci 0001:00:02.1: reg 10 64bit mmio: [0x730000-0x73ffff] pci 0001:00:02.1: PME# supported from D3hot pci 0001:00:02.1: PME# disabled pci 0001:00:03.0: reg 10 64bit mmio pref: [0x900000-0x9fffff] pci 0001:01:01.0: reg 10 32bit mmio: [0xa00000-0xa00fff] pci 0001:01:01.0: supports D1 D2
Bad (which is less verbose because it came from a console output): ACPI: PCI Root Bridge [P001] (0001:00) pci 0001:00:02.0: PME# supported from D3hot pci 0001:00:02.0: PME# disabled pci 0001:00:02.1: PME# supported from D3hot pci 0001:00:02.1: PME# disabled Entered OS MCA handler.
