If you don't have it you at least want the patch below. It generally
makes the bug non-fatal.
I'm still working my way through possible fixes... Although the
patch in question is close, and normally fixes it in my utmost
paranoia I can still find problems with it.

[PATCH] x86-64: survive having no irq mapping for a vector
Occasionally the kernel has bugs that result in no irq being found for a
given cpu vector. If we acknowledge the irq the system has a good chance
of continuing even though we dropped an irq message. If we continue to
simply print a message and not acknowledge the irq the system is likely to
become non-responsive shortly there after.
