This is the bug report:
https://bugzilla.novell.com/show_bug.cgi?id=260794

Klaus: Could you also attach acpidump output to the bug, pls.

This is not related to suspend/resume.

-> Good question, first I was sure to be able to always reproduce this
on 2.6.1[68] kernels with psmouse module compiled in. Latest .21-rc7 was
unaffected.
I then removed thermal, fan, processor module to not get loaded via
initrd (gets loaded later at init 3 or 2). Since then the symptom
vanished. (even after adding the modules again. Maybe I mixed something
up in the end, or the order of modules loaded in initrd changed, but I
doubt it was that...)

However, if someone should see any AE_TIME ACPI errors on an HP, I'd try
to compile psmouse as module or compile it out, chances are high that it
helps..., I wonder whether more people see this, would be nice to get
some more reports.
