Not sure if it's the same problem.  But we were seeing a miscompare on
2.4 due to a incorrect COW happening, followed by a hardware hash hole
w/ PPC64.

To fix it we had to make sure that the PTE was cleared and the TLB's
flushed before the new PTE was established.

Martin, was this fixed on 2.6?

Thanks,
Jake
