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
