I went through hoops and loops to get that lkp muck running, but as many
different machines I tried on it never reproduced.

So I need a bit of help from you folks. Can you please provide me:

   1) The exact host kernel version
   2) The config file
   3) The exact kvm-qemu version

Also it would be interesting whether 4f3f6d6a7f8e from that WIP.x86/ipi
branch in tip has the same issue on other host machines.

Another data point would be whether it depends on a particular compiler
Thanks in advance,


P.S: the instructions for reproducing the issue in that robot mail are
incomplete because there is no information how to bring the module into
that initrd... I somehow figured it out.
