OK, thanks.

If you have time, could you please test

2.6.21-rc5 +
ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.21-rc5/2.6.21-rc5-mm2/broken-out/origin.patch + ftp://ftp.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.21-rc5/2.6.21-rc5-mm2/broken-out/git-acpi.patch
which will allow us to eliminate any non-acpi patches.

Okay, I tested with those patches and got the same problems with the
resulting build.
I can't reproduce the hang on plugging in the AC with either
2.6.21-rc5-mm2 or the
build with the patches you sent. The other problems are 100% reproducible.
I have some new details:

1. Power always shows up as plugged in to AC.
2. The lid button is non-operational for initiating a suspend.
3. Suspending from the Gnome shutdown menu works. Afterwards, the
lid button works for resuming from suspend.
4. If I suspend, resume and then try to shutdown; when I see the
message "The machine will now halt" the power does not shut off. That
is, the various buttons on my laptop stay lit up. I am forced to
shutdown by holding down the power button for five seconds.

I hope this helps,
Miles
