[Xen-devel] dom0 doesn't init LSI Fusion-MPT, with kernel's option 'nosmp'

[Константин Алексеев <kv.alekseev@xxxxxxxxx>]

Xen 4.1.1, Kernel 3.0, Debian Weezy.
LSI Logic / Symbios Logic SAS1064ET does not initialized, if boot dom0
with kernel's option 'nosmp'.
Under native it does not happen.
With Squeezy i have the same bug.
