I had to back off to 7.3-R. Unfortunately the machine is the 'everything' 
server at home (routing, dhcp, storage, mail etc.) - so it wasn't proving 
very popular messing around with it :(

I put 7.3-R back on - everything works as it did. ZFS re-scrubbed the 
pools, and I'm good to go.

We have a 'very similar' machine at the office (same controllers etc.) - 
I'll see if I can get enough drives together and run that up. If that fails 
as well it's a much better platform to debug on :)
