I recompiled the kernel with full debugging again. Unfortunatly all I can get
out of it is the ddb prompt trace as the system does not get far enough into
boot to configure swap and a dumpdevice etc so I have no core dump.
Apologies if I have typo'd anything in here but I transcribed this by hand off
the screen. If there is anything else you need from that prompt let me know
and I shall reboot with the new kernel again and get it.
Matt.
