Wow - that seems to have worked! It still running through it's first
boot process, so I've not managed to log in yet. dmesg below.
But the "root device softraid not configured" and the "kernel: integer
divide fault trap, code=0" have usually happened by this stage in the
boot process.
What is really odd is the libretto does not have either an it or
schsio devices in it...
I'll confirm in the morning if I can log in.
Cheers
Fred
