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

hdb: start_power_step(step: 1000)
hdb: completing PM request, resume

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.)
