Hi!
This is a patch (very ugly, assumes you have just one disk) to bring
powersaving to AHCI. You need Alan's SCSI autosuspend (attached) patch
as a base.
It saves .5W compared to config with disk spinning, and even .15W
compared to hdparm -y... on my thinkpad x60 anyway.
It is also mandatory

It looks like this not a write-only variable after all...
Yep,
Hi!
So that's using the old IDE drivers.
And the network and USB are sharing IRQ#11 with each
other.
If you are going to be using newer kernels like this
(2.6.23+),
then you might consider shifting those drives over to
libata drivers.
Yes, that will probably fix it for him, but

Hi!

irqpoll option)

Your machine decided to emit interrupt 21 without an apparent reason.
Whatever caused that made the kernel shut down IRQ 21 at which point the
disk drives on that IRQ were

Oh... crap, so acpi wants to sync cache on shutdown. I wonder whether
it spins down the disk correctly. Does emergency unload count increase
after each power down? Also, please post the result of 'dmidecode'.

Hi!
When I reboot my notebook, it powers off and powers back on.
On poweroff a loud snapping noise seems to be coming from the
hard drive. Today I noticed there is no shutdown: hda on
the console when I reboot. Whne I do a normal poweroff the
message is displayed and there is no noise.

So if you have reported a regression in the 2.6.21-rc

problems with xyzzy).

Hi!
This patch is the result from the following discussion.

The problem is that CONFIG_PM affects a lot of low level drivers and
scattering CONFIG_PM all over the place is too ugly. This patch...

Hi!
Much complexity for little gain. Who is running _without_ CONFIG_PM
these days?
Embedded people, I guess. The problem here is that if we are gonna
support !CONFIG_PM configuration and try to reduce the kernel/module
images size for such case, we end up sprinkling #ifdef's all over
