shutdown problem with 2.6.7-rc2 / 2.6.7-rc2-mm2

[Jurriaan <thunder7@xs4all.nl>]

Both 2.6.7-rc2 and 2.6.7-rc2-mm2 don't shut down my systems anymore.
They print 'System halted.' but don't switch off.

This happens on a P4 (i875 chipset), a dual P3 (BX chipset) and a P3
Tualatin (830 laptop chipset).

I use Debian/Unstable (updated as of yesterday), and this worked on all
these systems with 2.6.6-mm4, mm3, mm2 and so forth, since a long time.

The last thing Debian executes is

halt -d -f -i -p

Compiling with ACPI Debugging on gives no interesting output. I've tried
searching lkml for similar problems, but I didn't found related reports.
Since I have it on three systems, I strongly suspect some change in the
kernel. If nobody pipes up and says 'see this post .....' I'll post my
.config, dmesg etc. but let's try this small post first.

Thanks,
Jurriaan
