    kernel 5.13.0 memory corruption

    Hi there,

    I´ve just built kernel 5.13.0 based upon my .config from 5.12.13.
    Now after booting 5.13.0 (I use memory_corruption_check=1) I get lots of memory corruption messages, looking like this:

    Code:

    I´ve used my well known .config from 5.12.13, I´m not aware if it contains trouble making values, I´ve uploaded my .config to
    Pastebin.com - Not Found (#404)
    https://pastebin.com/7xLMA6dy
    Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time.


    Can you cleanly boot 5.13.0?
    If you have a working .config for 5.13.0 I would be glad if I can see yours.

    Thnx a lot

    SOLVED
    For people who may face the same issue, now what I found out:

    I followed the guide at the "Kernel Self Protection Project" and enabled some (most) of their suggested .config settings. Among them boot option page_poison=1.
    I have now learnt, page_poison=1 is obsolete with 5.13, instead options

    CONFIG_INIT_ON_ALLOC_DEFAULT_ON or
    CONFIG_INIT_ON_FREE_DEFAULT_ON

    should be used.
    Thus, my fault. I dragged page_poison with me for years without checking for changes... *facepalm*

    5.13 seem to be an actual advance for AMD Ryzen APUs regarding temps/power consumption.

      It's a regression, apparently, introduced by commit 51cba1ebc60df9c4ce034a9f5441169c0d0956c0
