Bug#906769: arm kernels fail to boot

[Peter Palfrader <weasel@debian.org>]

Package: linux-image-4.9.0-8-arm64
Version: 4.9.110-3+deb9u3
Severity: critical
X-Debbugs-Cc: dsa@debian.org

The latest kernel fails to boot on our arm64 hosts at conova (Gigabyte
X-Gene MP30-AR0) and the VMs on those hosts.  Booting the old -7 kernel
works one those.

After grub, the last thing I see is
| OSBootEvent = Success
| L3c Cache: 8MB


Furthermore, arm-arm-0[134] are down.  According to our documentation
those are AMD Seattle rev B0, APM X-Gene, and AMD Seattle rev B1
systems.


Also, some 32 bit hosts appear to be affected, though I have
not yet looked into them in detail.  However,
abel and arnold, hartmann, hoiby (Armada XP GP), and henze (probably
also the same hw) are all down.

harris (imx53 QSB) booted just fine.  It's -- from a quick glance --
the only arm* host of us that survived this kernel update.

Cheers,
