Hi Neil,
It completed without apparent error (I did see errors in my very quick look!) - so I rebooted.
Unfortunately, it stopped in the same place. It ran for over an hour before I went out, it had stopped by the time I got back a couple of hours late.
I should have captured dmesg before I rebooted, but I didn't (I blame walking for almost an hour in the hot Sun...).
I will follow this with email with hopefully useful diagnostics...
Cheers,
Gavin
