[Bug 272247] Re: System freezes during boot, unless I hold a key down

[67GTA]

That is a seriously broken acpi table! I don't think you could even
begin to fix that. As you fix one error, 50 more will appear because of
the change you just made. The segmentation fault is because of the
maximum 200 error limit of the aml compiler. At that point I guess the
developers decided you should probably just start over. Have a look at
this section:

If (\_OSI ("Linux"))
                    {
                        Store (0x03E8, OSYS)
                    }

                    If (\_OSI ("Windows 2001"))
                    {
                        Store (0x07D1, OSYS)
                    }

                    If (\_OSI ("Windows 2001 SP1"))
                    {
                        Store (0x07D1, OSYS)
                    }

                    If (\_OSI ("Windows 2001 SP2"))
                    {
                        Store (0x07D2, OSYS)
                    }

                    If (\_OSI ("Windows 2006"))
                    {
                        Store (0x07D6, OSYS)

This is supposed to be the supported OS's for your machine. Obviously
your DSDT was compiled by the Microsoft aml compiler instead of Intel's.
If you care to test, try adding the entries above to your kernel line in
/boot/grub/menu.lst. Try acpi_osi="Linux" first to see if any of the
problems your having go away. If not, delete it and try the next,
acpi_osi="Windows 2001", etc... Spelling is critical. Here is mine for
reference:
