Arch as guest on Debian Host (KVM 64bit) - Newest Kernel doesn't boot

Hello.

As the title says I am running KVM on Debian (Lenny) using Archlinux as a guest.

I have upgraded a VM that is running nagios to the latest version and now the guest doesn't boot any longer. It just hangs. I've also tried installing a clean Arch system and it fails to boot as well.

Package that causes the problem: x86_64 kernel26 2.6.38.4-1. I am positive this didn't happen with 2.6.38.* (older than 4).

Here is a screenshot where it hangs while booting.

Any tips? Any information I can provide to assist further, let me know.

Best Regards.

Update
Using arch nolapic as a parameter in grub booted the system but I'm not sure what I am losing without this option (will have to investigate)

Update 2
Changing the CPU allocation to 1 in the KVM parameters for the guest also makes the boot successful. Anything other than 1 CPU hangs

Update 3
One of the Arch guest I had not updated had the following Kernel Version and booted sucessfuly with 4 CPUs

Here is the output of uname -a

Linux [host] 2.6.38-ARCH #1 SMP PREEMPT Wed Mar 30 08:47:36 CEST 2011 x86_64 QEMU Virtual CPU version 0.9.1 GenuineIntel GNU/Linux

Update 4
I have installed the LTS Kernel (2.6.32.39-1) and the problem I'm having with booting also happens. Something must have changed in the recent compilation parameters that caused this. Will file a bug.

Update 5
