How does Linux move from an awake machine to a hibernating one? How does it then manage to restore all state? These questions led me to read way too much C in trying to figure out how this particular hardware/software boundary is navigated.

    Maybe you have just ended up with a lemon CPU. Though for random crashes like that, I’d almost always look to RAM first.

    I did have some stability issues early on when trying to enable Expo. Never quite got that working right so it is currently disabled. I keep my 7600x in Eco mode since it is air cooled and the performance difference is not that great anyway, so I haven’t noticed any major differences with Expo off.

    The Expo issues were also with a very early MSI BIOS. I haven’t tried it again after upgrading, but I probably should.

      Yeah the goofy thing is it pass any length of memtest I care to toss at it, and will happily run prime95 forever with zero issues.

      And then immediately have apps crash or freeze or otherwise misbehave.

      Like, something is wrong, but nothing is actively broken, which is just… annoying, heh.

      The MSI board has been a source of less than enjoyable usage, but it’s almost exclusively tied to the super super long POST times and the fact that, sometimes, it just… doesn’t. Hard to know if the 90+ second wait is the normal 90 second wait, or if it’s actually not going to turn on for some reason.

      It’s fine other that little quirk, at least as far as I can tell.

        It volts up under load, maybe the problem is too little voltage at light loads.

          Well, shit. This may have led me down a useful path.

          So not voltage exactly, but load line calibration adjustments looks like it very much MAY have resolved the issue.

          Or at least, I’ve been whacking at it with all the workloads that were unstable and crashing and so far it hasn’t misbehaved at all.
