Did you have the problem straight from install, or perhaps when a new
kernel started being used ?

My system worked well for some months, there was no kernel update and
it started to go wrong a couple of weeks ago. I also see errors
when I run 'badblocks' -- which makes it smell of a hardware issue,
but the disks were tested, on return, by the hardware supplier and
they did not find any problem with them.

Given that you are not seeing anything in /var/log/messages make me
think that I do have some other problem -- perhaps in addition to
what you have.
