Ephemeral boot error: alloc magic is broken at 0x94eceac0: 94e05880

[David Britton]

Xenail, MAAS: 2.2.2-6099-g8751f91-0ubuntu1~16.04.1 (stable ppa)

I get the Following error on boot of my systems into the commissioning image:

Booting under MAAS direction...
error: File not found.
alloc magic is broken at 0x94eceac0: 94e05880
Aborted. Press any key to exit. error: you need to load the kernel first.

From our irc discussion:

18:27 < dpb> but it's booted just fine as recently as 2 days ago

A new grub version was published on 2017-07-28 in 2.02~beta2-36ubuntu3.12. This seems like it could be a regression in grub that 2.02~beta2-36ubuntu3.13 (currently in proposed) could probably fix.

I'm still getting this. I tried updating the NUC firmware where this repeats, no joy.

Maas version: MAAS version: 2.2.2 (6099-g8751f91-0ubuntu1~16.04.1). My images are all "synced" as of today.

Anything else I can try?

I found out a trick:

https://askubuntu.com/questions/760228/booting-under-maas-direction-error-file-not-found

This led me to think there was an error with the kernel selected for the ephemeral boot, so, I went into settings, 16.04 was selected, but the kernel was 'no minimum kernel'. I changed that to 16.04-hwe. I then was able to enlist. After that, I switched it back to 'no minimum kernel', and it still enlists fine.

I suspect some kind of migration is amiss, and it was trying to tell the node to use a kernel that was no longer there, or not referenced in the right way.

Anyway, appears working now with that workaround.
