    Subject[linux41] regression with 'x86/cacheinfo: Move cacheinfo sysfs code to generic infrastructure' on AMD i686
    From
    Date
    Hi Guenter, Sudeep,

    It now came down to 'x86/cacheinfo: Move cacheinfo sysfs code to generic
    infrastructure'[1] as you can see here[2].

    The facts are:

    - You can't boot on i686 only with more than one CPU core on AMD
    hardware (x86_64 however works)
    - Using Ubuntu config[3] it boots but creates an kernel >= 1 GB in size
    on Manjaro
    - By reverting 0d55ba4[4] the kernel boots.

    So we have to find out what is causing this issue[5].

    kind regards
