@cmb:
Yeah it's still building, should be done within a few minutes from the time of this post.
It's getting hard to tell the difference between the "crashing" I was experiencing and the newish problem with IPSEC tunnels failing to start at all although I think that should be fixed now I have resaved the config using the button at the top of the IPSEC page which I suspect puts in the results of some changes in the code.
I see rather a lot of snaps have come out recently and I've been installing them so let's see how it goes. My CF card is getting a good writing to. Let's call this solved for now and I'll start a new thread with a more useful set of diags if I still have issues.
Thanks for your comments and hard work, cmb and ermal.

[EDIT] Another crash. I've managed to boot this box with a serial to USB converter (Prolific) without it hanging so that's an improvement over older versions. I've passed that through to a Linux VM in VMware are connected it to "screen" with logging switched on. I can then watch that via ssh and screen on my laptop downstairs as well. With luck I'll have something better to report back with now I can see the console at last without having to sit in the attic!
