I have been trying a few things, can't get this to reboot with the root FS
as rw.
I have attached my original checkroot.fs which you sugested be edited
following your instructions below (Attached email).
I have provided the unedited version.

Hello James,
Sorry for late answer but I was worry about the new Randolph patch for the
N4k discontigous mm :-$

umm Thibaut seems to confirm the same pb I mentioned :)
and you could try it's tips but iirc it will not works (device busy :( )
Any way you have right: I forgot a lot of details.
For my part it was a external disk which I can mount on another parisc-linux
box to re-install previous initscript dpkg; then reboot, update patch the
kernel (sorry I don't have enough time to check if 2.4 included the willy's
patch) and re-install new initscript dpkg. (and last reboot to check the
patch efficiency :) )
OTC if it's an internal disk, it would be more helpfull to reboot from your
install cd and from the install menu launch a shell
(if you need you can have a look at
<http://lists.debian.org/debian-hppa/2004/06/msg00017.html>
where I explain in detail howto).
at this place create a /MNT dir on wish you can mount your root fs (mount
/dev/sda2 /MNT)
edit your /MNT/etc/init.d/checkroot.sh (pay attention vi doesn't exist on
your cd ramdisk but well nano :) )
and apply the tips I mentioned here
<http://lists.debian.org/debian-hppa/2004/03/msg00070.html>
(in essence insert '-t $roottype' in all mount cmd).
Here you would be able to reboot on your hd to update your kernel.
pff... less trivial then I remember, once again apologies but it was so
far ;)
That said if something is not yet clear don't hesitate to come back :)
hth,
Joel
PS: I was surprised that you were able to run a smp kernel on a N model,
hoppefully only one cpu exists or is configured :).
