Based on this suggestion and Julien's suggested patch on IRC a couple
hours ago, I've tested the attached patch successfully (as in: from a
busy loop in qemu-system-arm to the “expected” kernel panic, as
discussed in another subthread).

I've uploaded linux-image binaries (armmp and armmp-lpae) here, which
were cross-built through sbuild, thanks to Vagrant's suggestion on IRC:
  https://people.debian.org/~kibi/linux-bug-922478/

which is:
  DEBIAN_KERNEL_DISABLE_DEBUG=yes sbuild -d stretch-proposed-updates -c stretch-amd64-sbuild --build=amd64 --profiles='pkg.linux.notools nodoc nopython cross pkg.linux.nosource' --host=armhf linux_4.9.144-4.dsc

Checking this on real hardware would be great, trying to put everyone
involved in the loop through cc.


Cheers,
