    SubjectAPM Suspend Problem
    From
    Hi,

    Since about 2.6.0-test9, my ThinkPad T21 no longer suspends with APM. I had
    issues with it suspending before, I don't remember exactly what issues, but I
    know that it definitely worked in -test2. When I hit the key on my laptop to
    suspend, it will turn off the LCD and the HD will spin down, but the machine
    will not actually suspend. Here is what is printed out on the console when I
    hit the suspend key and then when I hit another key to "wake" it up:

    hdc: start_power_step(step: 0)
    hdc: 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
    hda: Wakeup request inited, waiting for !BSY...
    hda: start_power_step(step: 1000)
    blk: queue c138fa00, I/O limit 4095Mb (mask 0xffffffff)
    hda: completing PM request, resume
    hdc: Wakeup request inited, waiting for !BSY...
    hdc: start_power_step(step: 1000)
    hdc: completing PM request, resume

    I have attached the output of dmesg and my .config file. I am using
    2.6.0-test11, of course.
