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.

From 07f237b3911a685b18a7584456ace1293636bcc7 Mon Sep 17 00:00:00 2001 From: Cyril Brulebois <cyril@debamax.com> Date: Mon, 18 Feb 2019 13:49:50 +0100 Subject: [PATCH] Update debian/arm-avoid-abi-change-in-4.9.139.patch (Closes: #922478). This makes it take into account the function pointers reordering in arch/arm/mm/proc-macros.S (addition of check_bugs), fixing the failure to boot many armhf devices.
