Well, at least Intel acknowledges, documents and finally fixes these CPU bugs (via microcode updates).
AMD on the other hand doesn't even acknowledge an issue when multiple customers report problems. See this Ryzen bug: https://community.amd.com/thread/215773
Huh? There are plenty of AMD employees in that thread who have acknowledged the problem. They're "looking into it", but just seem to have no progress to report yet, and suck at keeping people in the loop.
And at least one person near the end of the thread reports the problem occurs when ASLR is turned on, for what it's worth: https://community.amd.com/thread/215773?start=105&tstart=0
>at least Intel acknowledges
Not in this case.
"Apparently, Intel had indeed found the issue, documented it (see below) and fixed it. There was no direct feedback to the OCaml people, so they only found about it later."
It was acknowledged, and documented in a errata bulletin, but not communicated back to the reporter. Assuming that it had not already been reported, discovered internally, or reported by another source. Seems more like sloppy followup on a bug report, which unfortunately happens in any large project.
The first reply is from an AMD employee..........
