I've now re-installed Mythbuntu 12.04.04, it's been up for some hours 
without a problem.
(I always erase the disk on install)

I have copied alot of the record-programmes backup onto the main disk again 
(this caused lockups before).
But I have not yet rebooted after the updates were applied.  The DKMS(sp?) 
process did fail trying to update some kernel module of the install though.  
The update window locked up on the first go, and after re-trying I got this 
failure (running in a shell).

Interestingly, even booting the install disk (both 12.04.04 and 14.04.01) I 
get a couple of random coloured characters on the display before it goes 
into graphics mode for the mythbuntu graphical booting-splash.

I'm so confident the box actually has a hardware problem that I've already 
selected replacements, and after 3 days of no  myth-tv, the SO has approved 
the purchase.  So the 12.04 re-install is just to convince myself to spend 
the money.

Still fingers crossed but.
