[ACPI] hard drive errors on acpi s3 resume

[sdfa <sli...@ex...>]

i've been trying to get s3 working on my sony vaio, but i'm having some problems concerning the hard drive during resume. after a resume i see these messages in dmesg:



hda: lost interrupt

 evevent-0299: *** Error: No installed handler for fixed event [00000002]

Restarting tasks... done

hda: dma_timer_expiry: dma status == 0x21

hda: DMA timeout error

hda: dma timeout error: status=0x50 { DriveReady SeekComplete }

ide: failed opcode was: unknown

hda: status error: status=0x50 { DriveReady SeekComplete }

ide: failed opcode was: unknown

hda: no DRQ after issuing MULTWRITE_EXT

hda: status error: status=0x50 { DriveReady SeekComplete }

hda: status error: status=0x50 { DriveReady SeekComplete }

hda: no DRQ after issuing MULTWRITE_EXT

hda: status error: status=0x50 { DriveReady SeekComplete }

ide: failed opcode was: unknown

hda: no DRQ after issuing MULTWRITE_EXT

ide0: reset: success



sometimes i also see this message right before all of this, i'm not sure if it's related:

acpi_bus_0200 [77] bus_set_power      : Device is not power manageable



the drive eventually spins up and the resume is a success, but it takes like two minutes(too long) and i'm afraid it may be damaging my hard drive.



the drive is an ide ata drive with an ich4-m controller.
