Subject: 2.6.21-rc[123] regression with NOAPIC

Hey there,

For me, this is a minor regression as I no longer need to boot with
NOAPIC, it just happened to still be the default when I tried 2.6.21-rc3.

During boot, the computer wedges, hard. It's unresponsive to SysRq
combos, or ctrl-alt-del, but the fan kicks in pretty quickly, so I'm
guessing the CPU is still going wild.

The boot locks right before, or during, or immediately after the ** line
below:

   [   15.020037] ACPI: CPU0 (power states: C1[C1] C3[C3])
** [   15.020221] ACPI: Processor [C000] (supports 8 throttling states)
   [   15.036059] ACPI: Thermal Zone [TZ1] (66 C)
   [   15.041893] ACPI: Thermal Zone [TZ2] (53 C)
   [   15.051285] ACPI: Thermal Zone [TZ3] (33 C)
   [   15.054922] ACPI: Thermal Zone [TZ4] (34 C)

This is an x86-64 system, HP/Compaq nx6125, ATI chipset (sigh). Booting
with NOAPIC worked in 2.6.20, fails in 2.6.21-rc1 (and 2, and 3). I
haven't started bisecting yet, as I'm going to start a painful suspend
to RAM regression hunt first.

Full dmesg from a successful 2.6.21-rc3 boot attached.
