    Default compulab fitlet2: general protection fault in kernel

    We have a number of Compulab Fitlet2 mini-PCs running on OpenSuse 15.1 (kernel 4.12.14) beautifully.

    Opensuse 15.3 (kernel 5.3.18) encounteres a general protection fault while looking at devices, most likely the power button.

    On leap 15.1 the kernel show no problem, eg:
    Code:

    And some time after (seconds to hours) the kernel apparently locks up.


    Does anyone have a Fitlet2 and solved this issue?

    Does TW or 15.4 alpha do the same thing as 15.3? I'd file a bug to bring this to the attention of the kernel developers. Atom users here seem to be few and far between.
    Reg. Linux User #211409 *** multibooting since 1992
    Primary: 15.3, TW, 15.1 & 13.1 on Haswell
    Secondary: eComStation (OS/2) &15.2 on i965P w/ Radeon
    Tertiary: Debian, Fedora, Mageia, more on Rocket Lake & older Intel, AMD, NVidia &&&&&

    Unknown. And it is difficult for me to test other kernels because it is a remote box under the physical control of a non-technical person. It took 4 days to get it downgraded to 15.1.

    I did google for the stack backtrace but I seem to be the only one who has seen it. I did see that the Intel BMC stuff has been refactored between kernel 4 and 5 so it is likely there is a regression there.
