    Hi,

    I'm trying to test out APM on my laptop (in order to test some PCMCIA
    changes), but I'm hitting a brick wall. I've added the device_suspend()
    calls for the SAVE_STATE, DISABLE and the corresponding device_resume()
    calls into apm's suspend() function. (this is needed so that PCI
    devices receive their notifications.)

    However, APM is refusing to suspend. I'm seeing the following kernel
    messages:

    Suspending devices
    hdb: start_power_step(step: 0)
    hdb: completing PM request, suspend
    hda: start_power_step(step: 0)
    hda: start_power_step(step: 1)
    hda: complete_power_step(step: 1, stat: 50, err: 0)
    hda: completing PM request, suspend
    Suspending devices
    Suspending devices
    apm: suspend: Unable to enter requested state
    Devices Resumed
    hda: Wakeup request inited, waiting for !BSY...
    hda: start_power_step(step: 1000)
    blk: queue c03a845c, I/O limit 4095Mb (mask 0xffffffff)
    hda: completing PM request, resume
    hdb: Wakeup request inited, waiting for !BSY...
    hdb: start_power_step(step: 1000)
    hdb: completing PM request, resume
    Devices Resumed
    Devices Resumed

    The "apm: suspend: Unable to enter requested state" occurs about 20
    seconds afterwards.

    (Note that APM worked fine with 2.2 and 2.4 kernels.)
