One thing I did spot from the syslog (attached to 477073) was that ubiquity had picked up that I had a RAID controller and had switched on dmraid. This system is so old that I'd forgotten about the raid controller (I had switched that off ages ago and use the 2 SATA disks as separate drives not a raid set).
So I restarted the install using the nodmraid option (in fact I switched just about everything off!!) but the problem persisted.
I've attached the 2nd syslog as it seems to show that ubiquity is re-instating the raid functions.
I inadvertently duplicated this bug under https:/ /bugs.launchpad .net/ubuntu/ +source/ ubiquity/ +bug/477073.
I've marked it so.
Interestingly I'm running on an amd64 system.
