You're right, the issue was caused by bbappend in one of my layers,
which bumps PE, so the 4.4 which had this bbappend sorted higher than
other versions, from bitbake-layers:

linux-yocto:
  meta                 1:4.4.22+gitAUTOINC+d9f20333c4_f4e52341c3
  meta                 4.1.33+gitAUTOINC+322fa5b279_a38cb20273
  meta                 4.8+gitAUTOINC+03bf3dd731_67813e7efa

You're also right that x86-base.inc isn't used anywhere in oe-core's
MACHINEs so it just confused me, that qemuarm explicitly selects 4.8
version even when there is no negative D_P and 4.8 is now default.

I didn't get that far to actually boot it yet, in my environment I need
http://lists.openembedded.org/pipermail/openembedded-core/2016-October/127512.html
for sysconfig to find the kernel.

When I've created /vmlinuz manually then almost everything was failing
to start for whatever reason (that's why I started checking the kernel
version as well).

Thanks
