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. Charlie
