[Bug 1716784] Re: Ephemeral boot error: alloc magic is broken at 0x94eceac0: 94e05880

[David Britton]

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.
