Bug Description

MAAS Version:


What happened:

When I boot EFI systems through MAAS, they get stuck very early in the PXE process. Commission/enlist/deploy are all affected.

From some debugging with andres:

Basically, MAAS now sends ""cc:{'datasource_list': ['MAAS']}end_cc"" in the kernel command line to select the MAAS datasource to address issues where cloud-init reads cloud-config from localdisk first.

However, the following errors are shown. Note that this only happens when booting EFI/grub. Any ideas?

error: syntax error.
error: Incorrect command.
error: syntax error.
error: Incorrect command.
error: syntax error.
alloc magic is broken at 0x3ec88940: 0
Aborted. Press any key to exit.error: you need to load the kernel first.

I captured this terminal output from a *good* (non-efi) machine on 2.1.3, in case it's useful. The EFI machines (*broken*) I have all don't seem to show this when booting, so I can't give you what is shown for those.

This was introduced to 2.1 with rev 5561, backporting a fix for Bug#1562323. pxeboot and uefi parse things just a little bit differently, so only uefi broke.

+ # Select the MAAS datasource by default.
+ "cc:{'datasource_list': ['MAAS']}end_cc",
