Bug Description

The kdump/crashdump kernel is panicing during boot on Bionic.

1) Install the daily Bionic server or desktop ISO
2) apt install linux-crashdump, say yes to kdump being enabled
3) Reboot so as to boot with the correct kernel parameter
4) Run:
    root@bionic-server:~# echo 1 > /proc/sys/kernel/sysrq
    root@bionic-server:~# echo c > /proc/sysrq-trigger
5) Observe that the crashdump kernel panics before booting with an out-of-memory error. Log below.

If I replace the bionic image with the artful cloud image, and repeat steps 2-4, the crashdump kernel boots and successfully stores the vmcore.

The full log:
