that's not really the x86 tree's fault, i've been carrying the fix for 
that problem in tip/out-of-tree for 1.5 months:

hm, i guess you mean you went back to the previous version?

i _did_ test it prior pushing it out and it passed 30 build+boot 
iterations until it ran into that tip/out-of-tree fix. I decided not to 
add it to auto-x86-next because it does not belong into the x86 tree.

you could also revert:

| commit 6ca7b49a8d6ca765426540c8902d89f1345b14af
| Author: Yinghai Lu <yhlu.kernel@gmail•com>
| Date:   Fri Jun 6 19:54:25 2008 -0700
|
|    x86: add SRAT parsing to 64-bit

which makes that acpi build bug not trigger in allmodconfig. But this 
just obscures the bug.
