find the patches in the debian/patches/ dir which the diff creates.
It might be worth looking at these, and revisiting the BIOS issue if (as
is unfortunately likely) if there remains an issue.

the DSDT when not internally handling the backlight etc.. There are also
a lot of OS specific paths in the DSDT for this code, making things even
more fun to trace.

induced rename / typo, as this method is mentioned for getting
brightness on a Windows Vista compatible box.
Did the bios update also mention any fixes for Vista compatibility?

also add acpidump output and also CC me,
pls.
I'll open a new bug (or bugs, keeping the STD issue separate) some time
next week when I'll have a little more time to play with debugging
things.
Thanks for your reply,
Regards.

presuming ACPI as a good starting point, since that is an area where
AC / Battery may make a difference.
Can anyone suggest a debugging procedure to identify the cause of a
softlock, and where would be appropriate (which category) to file a
kernel bug for this?

Can someone point me to the code that determines the voltage / amperage
pairings for CPUs in power saving mode? Is this handled by the ACPI bios
(bios function call), or does the kernel directly affect the power setting?

When I boot the computer with ACPI support, there's an audible hum that

This hum does not occur in windows, and when I boot with noapic
pci=noapic acpi=off in the kernel
this?
Suspend doesn't work out of box, I've not really tried to diagnose.

Are these problems real, or are they simply the symptom of decompiling
the SSDT in the absence of context from the DSDT?
