      Anybody know Supermicro's update stance with this? Have they posted anything?

      You beat me to it! I just found the Supermicro links and was about to post them here :D.

        Dell Advising All Customers To Not Install Spectre BIOS Updates

        Revert back to pre-meltdown/spectre BIOSs, or wait it out if you aren't effected.

          I'm researching our environment and right now, it looks like the beginning of armageddon here, lol... But I'm not worried about it too much.

          Yes, it can be bad, but I haven't seen enough to actually totally terrify me.

            Ours seem fine, so I'm leaving the Dell BIOS 2.7.0 on for now. I'll revert back only if we experience issues, but so far it's been just dandy.

              I'm not sure why he is bitching about it. If he has a better idea, put it down on paper and tell people to test it.

              Sometimes things are just messy. Blame Intel for creating crap to start with, not your fellow devs who are simply attempting to resolve a crap situation.

                He is blaming Intel. For giving guidance to the Linux kernel devs to write garbage hotfixes. That is the point of his rant.

                    He is saying that, but about Intel not the kernel developers. The hotfixes are crap because Intel is telling the kernel devs that the only fix is to turn things off, at a high cost(performance) and nobody will want to enable the fixes because of the cost.

                      Mine are also working well.

                        The performance hit are affecting every system though, not just linux. So where is Linus getting this idea that the performance hit can be avoided?

                          Intel had added features to the hardware like 12 years ago that could avoid major performance hit with the speculative execution bug. It took 2 of those years to actually get it right. For those first couple of years they actually had an even worse performance hit than the fixes we're seeing today. So nobody actually implemented the fixes, even after the performance was back up to snuff.

                              @dustinb3403 because he is Linus Torvalds. Most computers in the world use a kernel that he invented and is still actively involved with. What he says matters. You might not think so, but you would be wrong.
                              The current fix from Intel isnt the only fix. It is the only one Intel has released yet, and it is unacceptable to him. The entirety of blame here is with Intel. Intel needs to make a fix that is universal and wont cripple their customers. I would guess the guys at MS doing these fixes feel exactly the same as Linus.

                                  Intel has had to backpedal on supporting Spectre on some older chips.
