2.6.32-git1 boots OK with 2 CPU's.
2.6.32-git2 boots with "acpi=ht" but only one CPU appears.
With 2.6.32-git2 booted
# git bisect bad
tindog:/usr/src/GIT/linux-git # git bisect good v2.6.32
Bisecting: 4685 revisions left to test after this (roughly 12 steps)
[f6c4c8195b5e7878823caa1181be404d9e86d369] Merge branch 'for-linus' of
git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid

This is where I lose understanding of what I've done as v2.6.32-git1 and
-git2 are not accepted as valid revisions needed by git bisect.

Sid.
