| |
Since 2.6.0-test4, and in -mmX IDE power management no longer works for me. Using Fn+F12 to initiate APM suspend-to-disk, the suspend starts as normal, then the disk spins down, which is wrong, because the disk spins up again to perform the actual save-to-disk operation.
The laptop is a Sony Vaio 333MHz celeron, with a PIIX4 IDE controller.
This used to work fine in all previous kernels.
I get the following log messages:
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: a request made it's way while we are power managing --- power down/up occurs here hda: Wakeup request inited, waiting for !BSY... hda: start_power_step(step: 1000) hda: completing PM request, resume ... hda: lost interrupt
The hard disk won't allow any accesses any more.
APM suspend to RAM doesn't work properly on this machine, so I haven't tested that.
