I guess I wasn't clear enough.  The booting procedure reaches the point where 
udev starts and it first reports

  /dev/rootvg/rootlv01 clean    xxx  files   xxxx blocks
  /boot  clean     xxx files   xxxblocks

  the next group of lines report

no such device or file  /dev/videovg/videolv01      etc etc 

   the  videovg group  is just data for mythtv.  The boot procedure stops as 
usual and there is the usual ' Type Control-D to continue' but when the mtce 
shell is exited, the computer reboots.

I have found that the new Ubuntu finds errors with every drive I have on 4 
systems and I see this error regularly.  Suse 10.2, FC-6, Debian, Mepis, and 
Kanotix (Debian) never seem to see a problem. I am used to this Control-D 
message and exiting the shell.

I can issue no commands,  since booting never finishes.  This has been running 
just fine, and had rebooted a number of times with no problems.  There are no 
other distro's on the system which is FC-5 based incidentally.

I could use a liveCD to look at the drive, 'cept I have no clue what to look 
for.

Does that help, or do I just re-install?     Which might be quicker and less 
edifying.
