It takes an oops during IPMI initialization:

Hi Mark,

I have seen this issue previously. It would be specific to D05. I think 
that there is an issue with the FW in this board, in that DMI reports 
IPMI support incorrectly.

Could we add a kernel command-line to avoid IPMI detection from DMI, 
ipmi_si.trydmi=0

Thanks,
John

Full details here, including bisection information and full logs:

Unfortunately it looks like the bug has actually been around for a while
but wasn't stopping us getting to a prompt:

   https://storage.kernelci.org/next/master/next-20181210/arm64/defconfig/lab-collabora/boot-hip07-d05.html

and it might still be some unrelated hang there.
