    Thanks, yeah I think I’ve settled on the same conclusion. Everything else about the board seems totally stable, so it seems highly unlikely that it only manifests in clang.

    The only reason I’d think that clang was a canary for a deeper problem is that AFAIK it does a bit of multithreading in an early phase of the compiler, and if there were some sort of TLB sync issue that may be a fairly good canary for it. Large process, probably faulting in lots of pages with a bunch of threads running simultaneously would be a good test. Not a lot of apps behave that way.

    But for now this thing seems stable and useful.

    I ordered a nice little silent 40mm fan for mine, a ‘Fractal Design Silent Series R3 Black/White Silence-Optimized 40mm Case Fan’ from newegg.

    Almost imperceptibly quiet and keeps the thermals just as well as the stock fan.

    FWIW they seem to be shipping with an actual little cpu fan on top of the heat sink.

    Sadly the fan is *incredibly* noisy, and I think mine is failing after a few days of running. Will need to measure and get a replacement somewhere.

    Any updates on this? I’m seeing a similar rare lockup inside clang, and the default firmware is fairly old (17.02 I believe).

    As far as I can tell the board is stable otherwise, but it seems that this particular case is out of the blue and fairly well reproducible.

    I haven’t updated the firmware yet since it seems fairly perilous and unclear if it’d fix anything.
