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
# uname -r
2) The config file
3) The exact kvm-qemu version
# qemu-system-x86_64 --version
QEMU emulator version 3.1.0 (Debian 1:3.1+dfsg-8)

Also it would be interesting whether 4f3f6d6a7f8e from that WIP.x86/ipi
branch in tip has the same issue on other host machines.
yes. it has the same issue.
Another data point would be whether it depends on a particular compiler
the issue could be reproduced too when built with gcc-8
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.
Thanks for the input, we'll improve the tips.
