Unless you think that it will be helpful to test with the workaround, I
would prefer to test patches from llvm (it takes days to build FreeBSD
on a net5501...).

This proves it is useful to test with uncommon hardware, and I would
like to check the crypto engine, hifn(4) and glxsb(4) built with
llvm (that worked fine around january).

Thanks a lot, regards.
