Booted to login prompt once ... and twice. Much better ! :-)
Thanks a lot !
Not sure if it's related, but in the "good" boots (with the patch), I see a truckload of:
systemd-udevd[3264]: starting version 204 sr 2:6:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sr 2:6:0:0: [sr0] Sense Key : Illegal Request [current] sr 2:6:0:0: [sr0] Add.

etc...
I might have a crap coaster in that drive. It doesn't prevent the machine from working otherwise, so far...
Cheers, Ben.
