This regression apparently occurred very late in 2.6.24 development.  It
should be easy to pinpoint?

I noticed that ACPI_SYSFS_POWER was added in -rc8.
But neither enabling it nor disabling it resolves
the bug.

I will provide additional information if needed.

One of the following commits might be responsible:

Can you please check if reverting any of them helps?

I will, but what version should I test them with?
I'm getting rejects with 2.6.24 and I'm not really
much into C.

Would you be able to install git and use it for downloading kernel sources?

Yes, I can install it, but I'm not familiar with
it.

No problem.  http://linux.yyz.us/git-howto.html#getting_started should be
sufficient for starters and I'll tell you what to do next.

Installed git and pulled Linus tree, like
described in the howto.

OK, thanks.

We're going to carry out a bisection over several commits.

Please go to the linux-2.6 directory and do:

$ git checkout 88fb61e4ba263685a0d5b82c7e9cd6f22a9e6a9d

Then, compile the kernel and test it.

Done, the regression is still there.

Hm, there are no ACPI patches between -rc7 and this one ...

(in the linux-2.6 directory) please do

$ git checkout 3ce54450461bad18bbe1f9f5aa3ecd2f8e8d1235

(this should be 2.6.24-rc7, actually) and try to build and test this kernel.

Thanks,
Rafael

The regression is sitting between keyboard and
chair. :/ The testkernel wasn't working, so I did
a diff of the know to work kernelconfig and the
testkernel:

3,4c3,4
< # Linux kernel version: 2.6.24-rc7-midori20
< # Mon Jan  7 02:56:41 2008
---
> # Linux kernel version: 2.6.24-rc7-test2
> # Mon Jan 28 23:26:04 2008
273c273
< CONFIG_ACPI_SBS=m
---
> # CONFIG_ACPI_SBS is not set

I then compiled 2.6.24 with sbs and it works.
Don't know how it got missing, but I take the
blame. 

Sorry for my ignorance and thanks for the help,

Rolf
