    SubjectRe: 2.6.11-rc3-mm1: device_resume() hangs on Athlon64

    On my box (Athlon64-based) swsusp hangs forever in device_resume() called
    from swsusp_write(), although interrupts are apparently handled
    normally then (eg magic SysRq works). The last thing it says is:

    ACPI: PCI interrupt 0000:00:06.0[A] -> GSI 5 (level, low) -> IRQ 5
    PCI: Setting latency timer of device 0000:00:06.0 to 64
    ACPI: PCI interrupt 0000:02:00.0[A] -> GSI 11 (level, low) -> IRQ 11
    ACPI: PCI interrupt 0000:02:01.2[C] -> GSI 11 (level, low) -> IRQ 11

    When I press Alt+SysRq+p it says:

    SysRq : Show Regs

    This happens 100% of the time. It also happened on 2.6.11-rc2-mm2, but not on
    2.6.11-rc2-mm1, AFAIR. It does not occur on the -rc[1-3] kernels.


    - Would you tell me, please, which way I ought to go from here?
    - That depends a good deal on where you want to get to.
