I think I have discovered the problem, the SD card is faulty/wearing
out.  I just tried to boot the system with a display attached and it
sits repeating an error message about "bcm2835 timeout waiting for
hardware interrupt".

Putting the card in a reader in my desktop machine it gets read
**very** slowly and times out before the automount completes.

I think a (some?) new SD card is on the agenda! :-)
