The specific problem with this notebook is that if anything is plugged
into a USB port, it will not boot.
The problem appears to be related to a buggy DSDT. I disassembled my
original DSDT using Intel's iasl compiler/decompiler from
http://www.intel.com/technology/IAPC/acpi/ and instructions from
http://forums.gentoo.org/viewtopic.php?t=122145 . The instructions
basically were:
cat /proc/acpi/dsdt > dsdt.dat
./iasl -d dsdt.dat
I have a "fixed" DSDT.aml which I have loaded via initramfs-tools and
which fixes the problem as far as I can tell, but this shouldn't be
necessary as Windows loads fine. The fixed DSDT.aml was obtained here:
http://acpi.sourceforge.net/dsdt/view.php?id=735 .
I have attached the original disassembled dsdt.dsl, as well as the same
file after loading the 'fixed' DSDT.aml using initramfs-tools / initrd
method, and confirming that the notebook boots with a mouse plugged in.
There are some obvious differences between the original (broken)
dsdt.dsl and the 'fixed' dsdt.dsl from my quick look, but I don't know
enough about ACPI to know what's going on. Hopefully this can be pushed
upstream for resolution?
