I quick google search suggests that at least some of them are too old to support SNA.

Sounds good. If you can capture the error as Daniel suggests, that would be great. In any case, I'll post a revert of the semaphore enable patch as it looks like that's still not working right...

Could we revert it for SNB, and leave it enabled for IVB?

It would be just the chunk which checks for intel_iommu status in the patch.
