    Yes, at first we were talking about x86 and kmemleak but leter on, the
    problem seemed more related to x86-64 and the config_no_bootmem option.

    Yes, but you seem to get it at each boot and immediately, which was
    never my case (don't know about Zeno). With I got it only once
    in several days of uptimes and boots.

    I hope your specific situation will help isolate the problem...
