[PATCH 0/6] SATA use ACPI methods for PM

[PATCH 0/6] SATA use ACPI methods for PM

[Randy Dunlap]

This is an update to the SATA suspend/resume patches
to use ACPI methods (specifically _SDD and _GTF).
This patch series applies to 2.6.15-rc4.

It boots but needs lots of testing & review/comments,
as well as adding a call to write taskfiles on
COMRESET event(s) (at least on async. loss of signal).

This is not intended to be a final patch for merging.

The patchset begins with the libata suspend/resume patch from
Jens Axboe and builds on that.

This sequence of patches FIXED the problem I was having
until now with my Dell Inspiron.  It usually fails the
suspend/resume (RAM) test with a Hitachi 80GB drive installed,
but this patch series makes even that combo work just fine.

The regular Fujitsu 100GB drive works regardless,
so long as Jens' original patch is applied.

Thanks.  I'll see if I can mold it into something acceptable,
although Jeff still hasn't commented on it directly....

Now that activity and discussion seems to have died down a bit, could 
you resend the latest versions of these patches?

Yes, I'm updating them a little and will try to resend
later today.

more comments:

Yes, the patch still contains some debugging code.
If you try it out and have problems, please give me as much of
the debug output as possible.  It is likely that I will also
want to see your ACPI tables.  To dump those, use
'acpidump' from the latest pmtools release at:
  http://www.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/

The patch series is available at:
  http://www.xenotime.net/linux/SATA/2.6.15-rc/
