Bluetooth adaptor suddenly not found

[Pete Smout]

Hi all,
Running a fresh up-to-date version of (X)ubuntu on a new (to me) laptop.
When I first installed it a week ago, bluetooth was working fine with
no issues at all, at some point it stopped finding the adapter at
boot.
I've tried going back to a previous kernel with no luck.
Result of lspi:

As you can see no bluetooth adapter found? It  was there where has it
gone any clues?
