linux-next-20080519 does not boot

[Sitsofe Wheeler]

While trying to boot this kernel the kernel seems to be going well until it
comes to time to mount disks at which point it starts going very slow. It
doesn't respond to the keyboard (caps lock does not work), sysrq is
inoperable and the ATA tests timeout and over the course of minutes start
negotiating slower speeds. Using nmi_watchdog=1 or nmi_watchdog=2 does not
make any difference. next-20080516 booted correctly.

Config is downloadable from http://sucs.org/~sits/test/config-20080519 .

OK I've finally bisected this down to the following commit:
commit 86a2e1a7ec8c6363e502ac8ccf5fe50dd46b39c2
Author: Alexey Starikovskiy <astarikovskiy@suse.de>
Date:   Wed May 14 19:02:57 2008 +0400

    x86: complete move ACPI from mpparse.c

    Signed-off-by: Alexey Starikovskiy <astarikovskiy@suse.de>
    Signed-off-by: Ingo Molnar <mingo@elte.hu>

Reverting that commit made the problem go away.

Here's the bisection log:

Hmm. Looks like I spoke too soon. This problem doesn't occur with
next-20080522 .
