    Meltdown and Spectre

    I've been looking around for anything on the various Fedora sites about these CPU bugs. News reports suggest that fixes have happened for Linux. It would seem that with such a hot news item (probably more than a little overblown), there ought to be some news from Fedora about whether the fix is done or in the works, and maybe which packages are pertinent.

    It's not official but there's an article here: https://fedoramagazine.org/protect-f...stem-meltdown/

    that's as near official as you'll get from Fedora Project. Paul W. Frields is involved in the Project (has been near enough from the start)

    Re: Meltdown and Spectre

    I wondered why kernel 4.14.11-300.fc27.x86_64 was built yesterday and wound up in stable today. That's super quick turn around for a new build. That's also the build that the article indicates fixes meltdown.

    Unfortunately, my aging Gigabyte MB can't boot this release. Think I'll wait for a follow-up release before jumping into debugging the "boot hang".

    No comments on the Intel CEO all the shares he could in December? I'm sure if I acted on insider info like that they'd offer me a stay courtesy of her majesty's prison service.

    well he had some sense doing that and I'd have done the same in his position. Intel can spin it any way they like, but to me it isn't coincidental he sold his shares after they were informed of the vulnerability. they were his shares to sell and if there were an issue, it would have been mentioned by now in the news about him being investigated for it.

    Noticed that too. Fedora project people did a very good job.

    I'm not convinced that the software fixes are sufficient:

    Those less paranoid might recognize December as a typical "use it or lose it" date to exercise your employee stock options. As CEO I'm sure he gets more options that the average employee

    But if he held the stocks and the company met the companies expectations that he and the CFO have been stating he would have made about US$1.3million per year until 2021 from the stock he sold. The fact that he sold *every* stock he possibly could is odd, it was flagged as such before the announcement was even made:

    I don't see how they can't at least investigate this.

    Re: Meltdown and Spectre

    I yield the point

    As an AMD user, I'm not at risk for the Intel issue. However, I'm suffering from the 4.14.11-300.fc27.x86_64 fix with 2 out of 3 boots failing to complete. Nothing surfaces from the journal logs. (maybe its completely coincidental hardware fail, but I doubt it )

    My F26 x86 4.14.11 system also hangs during boot after starting the window manager -- the screen remains in ascii mode with the usual boot log. Fortunately, I am able to boot into 4.14.8 .

    @Kobuck and normvcr, have you tried the steps in the "how to turn it off" thread in this forum?
