Worked out how to do it...  Edited /etc/default/grub removed "quiet" and
added "earlyprintk=vga debug" to GRUB_CMDLINE_LINUX_DEFAULT and ran
update-grub.

The bad news is that it hangs at the same point:

[    0.058517] CPU 1 irqstacks, hard=f75be000 soft=f75c0000
[    0.058551] x86: Booting SMP configuration:
[    0.058583] .... node  #0, CPUs:      #1

I had a look in the BIOS and the only thing that looked vaguely
interesting was "Execute Disable Bit" - "Intel Extreme Disable Bit
Function.  Supported CPUs can help protect from virus and malicious buffer
overflow attacks", but that didn't make any difference.

Had a read through the link Ben Hutchings sent
(https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html)
and ended up with:

GRUB_CMDLINE_LINUX_DEFAULT="earlyprintk=vga,keep debug udbg-immortal
ekgdboc=kbd"

But that didn't give any more info. :(

Thanks,
LJ
