| |
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.)
