This one:

?
CI does not think they are old warnings and registers are the MCR affected range. So more digging would be needed to be sure. You are saying those happen in our CI without the patch?
Then with regards to the reported perf drop - something to check would be if the CML system you tested on has the same slice/subslice config as the one from which the original report originated. Might be hard if the test farm has been re-configured. But essentially running the benchmark on a few Gen9 machine with fused ss would be needed I think.
And finally I couldn't find the WA entry in bspec, but maybe I just don't know where to look. Someone better versed to finding WA. Maybe Matt you would have time for a quick check if WaProgramMgsrForCorrectSliceSpecificMmioReads is documented as applicable to Gen9?
Regards,
Tvrtko
