[ACPI] Fw: 2.6.11 and later freeze without processor.nocst=1

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

You may need to raise a bug at bugzilla.kernel.org (against ACPI) for this.

Please mention that nocst isn't documented in
Documentation/kernel-parameters.txt, too.

Subject: 2.6.11 and later freeze without processor.nocst=3D1

Kernel versions 2.6.11 and later refuse to boot on my Asus P4V8X-X
board without the processor.nocst=3D1 option on the kernel command line.
Earlier versions work without any issues.

Is there any information I can supply to help fix this?

The kernel log from booting looks like this:
