Attached boot.log{F827345}

I just did a fresh install onto a new HDD. I choose to encrypt the swap volume and got a peculiar set up with the boot timing out waiting for a phantom luks volume group. iirc, the swap partition was luks only with it showing as mounted as a separate volume with the gnome disks gui - unlike the luks root partition which showed as I expected as a luks partition with an ext4 partition beneath it (but, with swap beneath the unlocked luks). I'm really sorry about all this gui description.

I've deleted the swap partition and the luks partition it was under and started again. This is what I have now:

:~$ lsblk -f

Which looks pretty sensible to me. I've come to that after manually editing fstab, crypttab and grub. Grub looks like this:

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash resume=/dev/mapper/luks-1e3960f9-89fa-4ffb-a77e-c829d2f1ca73"

The systems booting, suspending and resuming, but it's wasting 1'30" waiting for

Volume group "luks" not found
Cannot process volume group luks

Attached also fstab{F827348} and crypttab{F827347} (btw, I did some editing of those files between the boot.log at 17:44:21 and 17:53:15).

Any ideas where this phantom lvm group comes from (if that's what it is):

:~$ sudo lvm vgscan
