Public bug reported:
After upgrading Ubuntu 16.04.2 LTS to the current set of packages today,
a server failed to boot. The server is a file store and has lots of
disks. Only GRUB prompt came up after boot (thus UEFI managed to load
grubx64.efi, but it did not manage to load kernel). The prompt was
unstable. For example during one boot it was possible to use ls to list
partitions, but load kernel, but during another boot even running 'ls'
resulted in an "out of memory" error.
The server has 40+ disks attached in JBOD configuration where several
disks are using multipath. Thus the number of disks the system thinks it
sees is around 70 at boot time.
When only the ZFS pool containing the filesystem was left connected, the
system booted with grub 2.02~beta2-36-ubuntu3.11. Downgrading the
packages grub-common grub-efi-amd64-bin grub2-common to
2.02~beta2-36ubuntu3 fixed the boot problem with all disks attached.
Thus something got broken between 2.02~beta2-36ubuntu3 and
2.02~beta2-36-ubuntu3.11 that renders systems with dozens of disks
unbootable after upgrade.

Description: Ubuntu 16.04.2 LTS
Release: 16.04
The apport report is edited. Firstly there are lots of lines like the
following:
hostname systemd-udevd[8804]: Process '/usr/bin/partx -d --nr 1-1024
/dev/sdae' failed with exit code 1.
Secondly, since it did not boot properly with GRUB
2.02~beta2-36-ubuntu3.11, it was run with after booting up with
2.02~beta2-36-ubuntu3
