Latest 2.6.33 git(30ff056..) failed to boot on a x86_64 box
with errors during mptsas/mptbase initialization. I also
noticed a warning during ACPI initialization.

Performance Events: AMD PMU driver.

I observed similar failure with x86_32 as well.

2.6.33-git5 (847f9c6...) worked fine.

Have attached dmesg log.

Thanks
