Meaning the messages continued for as long as the system was under obse=
rvation.

I believe they are. Working in the sense that I can read off data
using 'dd', I can inspect partition tables etc.

The system was running overnight when I first hit the problem. On
subsequent reboots, I've only waited less than half an hour. Usually
the mount is instantaneous, so I wasn't sure if waiting would help at
all. The error messages did not indicate that the system could recover
at that stage. If there's even a slight chance that the fs would
eventually mount, I'm happy to let it run for a day or two. Note that
if I mount using the 'degraded' option, the mount succeeds but
subsequent attempts to read the data fail.

sigh, I feared as much.
