Bug#637308: xen-linux-system-2.6.32-5-xen-amd64: with kernel option 'nosmp', dom0 hangup while init PCI-Express Fusion-MPT SAS

"For optimum performance when running both CPU and I/O intensive
instances, it’s also recommended that the dom0 is restricted to one CPU
only, for example by booting with the kernel parameter nosmp."

Also this benchmarking advises disable smp http://web2.clarkson.edu/class/cs644/xen/files/repeatedxen-usenix04.pdf
