16.04 slow boot

[workshop99]

I've been using 14.04 for a year with sub 15 second boot times from an old SSD.
Installed 16.04 on new SSD and OK at first but now taking > 90 seconds to boot.
Complete dmesg output here: http://pastebin.com/zg0A2Eip

Extract below, note gap from 7 seconds to 97.

I've tried setting IPv6 Method: Ignore in System Settings, Network but made no difference.

Any suggestions, please?

I found this http://askubuntu.com/questions/63955...h-ubuntu-15-04
The problem was that I'd moved the swap partition using Disks but the original entry in /etc/fstab remained unchanged so at boot it was looking for a partition that wasn't there.

Ran into this myself lately and this thread really helped me out.

Experiencing the same, but perhaps different. Any ideas?
