hi,

things work perfectly fine on my desktop. but on my laptop (toshiba
satellite) if i try,

%hdparm -Y /dev/hda           <--- put to sleep followed by
%hdparm -C /dev/hda           <--- query status

gives me

hda: lost interrupt
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: irq timeout: status=0x50 { DriveReady SeekComplete }
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: irq timeout: status=0x50 { DriveReady SeekComplete }
hda: lost interrupt
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: irq timeout: status=0x50 { DriveReady SeekComplete }
hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma_timeout func only: 14
hda: irq timeout: status=0x50 { DriveReady SeekComplete }
hda: DMA disabled
ide0: reset: success

if i try the above from X, the machine freezes and i need to do hard
reboot.

the boot message regarding ide are as follows

boot messages

Uniform Multi-Platform E-IDE driver Revision: 6.31
ide: Assuming 33MHz system bus speed for PIO modes; override with
idebus=xx
ALI15X3: IDE controller on PCI bus 00 dev 20

    ide1: BM-DMA at 0xeff8-0xefff, BIOS settings: hdc:DMA, hdd:pio
hda: TOSHIBA MK2018GAP, ATA DISK drive

the closest i think i got to on google is the following but there are no
answers
