Re: 2.6.26-rc9-git9 doesn't boot on Macintel

I looked at your dmesg from 2.6.25.10

it tried to use mmconfig, and later fall back to conf1, because
1. your MCFG said it support bus [0,255], and range will be
[0xf0000000, 0xffffffff]
2. firmware only reserve [0xf0000000, 0xf4000000)

and 2.5.25 will not check acp reserved range.

from 2.6.26, it will check if the [0xf0000000, 0xffffffff] is reserved
via acpi dsdt _crs?
it will fail too.

So MCFG table is broken.

You need to get firmware update from your vendor.

or we need to put that system on DMI check to change end_bus_number
from 0xff to 0x3f

ps: mem=2g will not work, it will can not change mcfg table etc... you
need take out 1G ram out.
