[PATCH 0/3] [2.6.25-rc5] Handle a common BIOS bug on recent ASUS BIOS updates gracefully

[Thomas Renninger]

Hi Len,

the first patch fixes a memory corruption in ACPICA.
Memory corruption should legitimate this as 2.6.25-rc5 material (also
because this looks rather safe to do and seem to pop up on a lot recent
BIOS updates).
The second patch catches the NULL pointer which is passed on
evaluate_reference now, instead of a corrupted pointer.
The third patch tells the user that his BIOS has an invalid reference as
a passive cooling device (the invalid reference is the NULL handle now).

I have checked this working (ran into the corrupted memory and NULL
pointer) by invalidating a passive trip point and simulate the broken
ASUS BIOSes by overriding a DSDT on another system.

The first report which verifies the patches working with a 2.6.24 kernel
patched on a real broken ASUS Bios can be found here:

Comment #40:
"Works on the Asus M2N-E and M2A VM HDMI."

Thanks,

  Thomas
