Yeah, I did find a few references to this problem on the web but they 
didn't seem to have any kind of solution, or even a guess at what the 
problem was. I guess maybe it could be many different things.

I have no problems with the 'syncing disks' thing when rebooting 
normally. I shalln't pretend to know what I am talking about, but 
perhaps it's just some lock being held somewhere or something that 
prevents it from doing a forced 'sync' after hitting ctrl+alt+esc.

Anyhow, it does appear to dump properly with the 'reboot 0x104' one, so 
I just hope that if I ever get a real panic (and I haven't had one yet, 
which is nice!) it will dump properly :-)

Thanks again
