IDE, putting HD to sleep causes "lost interrupt"

IDE, putting HD to sleep causes "lost interrupt"

[Mukesh Rajan]

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

pci=biosirq.

    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

Well, the answer is very simple, then:  DON'T DO THAT.

When an ATA (IDE) drive is put to sleep (-Y),
it *requires* a reset to revive it for any future commands.

The IDE driver doesn't know about the -Y, so it just attempts
I/O a few times before digging out the BIG hammer and doing a reset.

All is well.

Would it be a reasonable thing to include the -Y information in the device
status so that the driver could know a reset was required? Since the
driver sends the command it has the chance to notice there, or might read
a status, or ??? Or is this undesirable for some other reason?

Because you need to call

hdparm -w /dev/hda		<--- Reset Device
hdparm -C /dev/hda		<--- query status, repeat until good.
hdparm -X** /dev/hda		<--- transfer rate mode set
hdparm -m** /dev/hda		<--- set multiple
hdparm -d* /dev/hda		<--- set DMA

You effectively kill (disable command mode) the drive has to be kick
started.

Cheers,

Well, mind how horribly that sucks if your hdparm is on the disk you've 
sent to sleep. Thus, never send your disk containing /sbin to sleep...
