Hi,

I've been running SL6.4 for the last few years with no issues.  The 
computer is left on all the time as it is providing weather data to a 
server.

Last weekend it was shutdown normally and on powering on again it 
fails to complete the boot sequence.  It displays the splash screen 
with Scientific Linux and the 'circle', the circle fills in and then 
disappears followed by nothing else happening.

I booted the computer using a live CD (Puppy) and can mount the root 
LV but not home.  Looking at /var/messages shows the boot log for the 
previous successful boot in September and the successful shutdown.

Any ideas?

Thanks in advance

Chris
