[Bug 1798679] Re: 18.10 installer crashed just after time zone selection

[rbmorse]

Hi Mathieu.

The system (ASUS X97) has only one disk attached, an Intel series 320
SSD in M.2 form factor with the motherboard configured to use the M.2
slot as NVMe. The disk is partitioned as a GPT device, with one (empty)
EXT4 partition when the install starts.  The install medium is a USB
connected flash memory device. The selected install option is the first
one for systems with no existing operating system detected.

The installer proposes creating two partition, the EFISYS FAT partition
and the remainder of the drive an a single EXT4 partition.   I accept
this and ensure "format partition" is selected.  The confirmation dialog
indicates these choices are selected

Postmortem shows the EFI partition is created, the EXT4 partition is
not.

I am told this morning by a source of unknown reliability that my
particular motherboard (ASUS Z97Pro) does not support booting from an
NVMe device.  This could certainly be the case.

The Intel device works fine for storage in a live session when mounted
manually.

I can install Cosmic to the same system if I add a Samsung 580EVO SSD at
port SATA0 and use that as the install target. If specified, the
installer will properly set up the Intel device as an additional storage
medium.

So, given that, at this point it appears likely I experienced a
motherboard limitation rather than a bug in Cosmic.
