Bug Description

When I boot a node into 'rescue mode', it is booting into 4.13 kernel.
the maas has no minimum kernel set (globally) nor does the node.

$ maas crash-and-burn maas get-config name=default_min_hwe_kernel
$ maas crash-and-burn nodes read
        "min_hwe_kernel": "",

Can you provide /var/log/maas/rackd.log when the machine is PXE booting and the MAC address of the PXE interface?

Well, in order to fix an issue where nodes were "stuck" in "exiting rescue mode", I restarted region and rackd. Next time I put into rescue mode it booted 4.4
