I finally got time to work this one out. Sorta. Thought I'd post for the
sake of the archives.
There were two problems:
- There was an extraneous kopt_alt_26 (I think) line
in /boot/grub/menu.lst, which means that instead of having
'root=UUID=xyz', it had root=/dev/md5. I removed this line, leaving just
the kopt= line, with the correct root= argument and reran update-grub.
- My /etc/mdadm/mdadm.conf file was subtly wrong: the last two
colon-separated fields on the ARRAY lines for md4 and md5 were wrong.
The first two were correct. I have no idea how it got into this state.
Anyway, I ran 'mdadm -QE --scan', and replaced the relevant lines
in /etc/mdadm/mdadm.conf with that data. Then I ran mkinitramfs to push
that change back into the initrd.
Et voila! It boots again. I can only assume that the reason the old
kernel still worked was because it somehow had a correct mdadm.conf in
its initrd, though I'm utterly puzzled at how it ended up in this state
Thanks to everyone for their help on this.
James.
