ERROR:  Poky's config sanity checker detected a potential misconfiguration.
    Either fix the cause of this error or at your own risk disable the checker (see sanity.conf).
    Following is the list of potential problems / advisories:

    /proc/sys/vm/mmap_min_addr is not >= 65536. This will cause problems with qemu so please fix the value (as root).

To fix this in later reboots, set vm.mmap_min_addr = 65536 in /etc/sysctl.conf.



The bug occurs after http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=6030fd77aa94f63f4d5babe1ffac1e40e15ee3f1

A change was made to the sanity checker since Qemu was fixed to not have to have the mmap_min_addr set to zero.  The auto builder was not changed yet.  This is
fixed on the autobuilder now
