Hmmm, that means (I think) that the root partition has failed the check
(obviously) and then you get a root prompt to try to repair it and
continue the boot. Now, it should have printed _which_ partition failed
the check. Which one was it?

Let me see if I undertand correctly. You are trying to boot to the _new_
install that apparently is in /dev/hdb3, right? Specifying root= in the
boot command line? I'm not sure I'm following what you are doing,
exactly (it has to be "exactly").

Yes, at that point you don't have a "working" "/" because it could not
be checked. So, the kernel is either trying to boot into /dev/hda2
(which is known broken), or /dev/hdb3 is also broken (unlikely). When
you say you got to /etc, how did you do it? 

Things I would try:

- try to boot into /dev/hdb3 (this assumes the install was fine). When
you get to the grub screen highlight the original redhat kernel (not the
Planet CCRMA one), press "e" to edit, go to the kernel boot line, press
"e" to edit, make sure the root= option is pointing to /dev/hdb3, press
"b" to boot from this kernel with the options selected. 

- if this does not work then probably the hdb3 partition does not
contain a valid install (depends on how it fails).

Could be a hardware failure or could be a kernel problem (unlikely but
possible). I doubt that Ardour was the cause of what happened.
