["Yu, Ping Y" <ping.y.yu@xxxxxxxxx>]

In our nightly test, we found the following block issue in latest 
change set, which can block our nightly testing. 
Could anybody have a look at this issue?

(1) IA32/PAE/IA32E: Linux guest OS may fail to boot up normally in VMX
domain, guest OS complains with the one of following info:
-- "BUG: soft lockup detected on CPU#0!"
-- "Kernel BUG at include/asm/spinlock.h:146!"

See attached snapshot.

The reproduce step is:
----------------
1.Preapare a Linux Guest OS image
2.Preapare a configuration file with vcpu=4, acpi=1, apic=1
3. xm cr "configuration file"

(2) In x86_64 platform, Windows XP and Vista UP VMX domain causes Xen0
hangs.
Keir will have a look at this.
