Re: IDE drive won't come back after power down

[Andre Hedrick]

Greetings Ross,

The problem is that the requirements of ACPI is to have a
"taskfile register access", but that will not be accepted until 2.5.
Therefore, the short nice answer is that you and everyone else with a
laptop of system using ACPI are "HOSED".

I will be happy to provide you the TASKFILE code, however ACPI does not
yet have a method to call the kernel direct access.

Maybe when there are enough people screaming and raise general hell over
the issue it may happen earlier.

You can attempt the noisy reset additions to some versions of hdparm, and
then issuing the the checkpower commands until staus is reported as ready,
but that is very messy and you have to have that app in an accessible
location and that is not usable.  The obvious reason is that the app is on
the disk that is spundown.

This is not the answer you wanted, but it is the cold bloody truth.

Regards,

Re: IDE drive won't come back after power down

[Ross Boylan]

Thanks for the diagnosis.  My system is a tower, not a laptop, but I
think it does have ACPI.  I infer this from the kernel MS W2K picked
out and the recency of the motherboard; I don't see it mentioned in
the M/B docs.  Should any ACPI system have the problem, or only
laptops?

It sounds as if the easiest thing might be to disable the spin down of
the disk.  Is there a way to do that?

I'm not versed enough in the details to understand the work-arounds
you propose below.  If I had the TASKFILE code, what would I do with
it? 

Is the noisy reset option a way to spin the disk up before there's
trouble?  Perhaps I could stash it on a RAM disk.

Thanks.

P.S. I'm right across the bay in SF.

My PC110 does the same as Ross' machine, and like this box it has no ACPI.
This isnt an ACPI problem on the boxes I've seen do it.

Any reason you cant do that in kernel space, if an app can do it then
pm thread code can do it ...

That is the prefered location; however, setting/writing up hold over code
that will be deleted in 2.5 is silly.  The basics are the non-data
taskfile registers operations.

Thoughts of accepting patches early for taskfile now?

Well if you can do it already in userspace via ioctl clearly the needed
kernel code is small
