I'm looking at updating the errata for old AMD CPUs and would like more precision on which CPUs work
and which don't.

Athlon 64 x2 and Phenom II x4 are confirmed not to work. It appears anything less than Bulldozer, which
introduced AVX, will not work with all algos.

If no one has data that says otherwise I'll update the errata in the OP.

These CPUs are working fine with legacy versions on zr5 algo.
I haven't tested other algos, since I have no interest in them.
m7m also works if I recall corectly - will test that on a weekend.

Thanks, that helps localize the incompatible code, it's not in code used by zr5 or m7m.
Let me know if something is broken using an AVX enabled AMD CPU, that would be
unexpected.

If that can help you identify (and hopefully fix) broken algos, I will do a full test tomorrow on all algos supported on zpool.ca.
That includes Linux and Windows builds of legacy versions (since they are faster on these CPUs).

I appreciate the effort but It's not something that I can fix easilly, so the work would only be for information purposes.
My main focus is on the newer architectures so I want to make sure all algos work on AVX enabled AMD CPUs.
Any problems with them would need to be fixed.
