This morning I wanted to make a change in the server's BIOS, so I had to 
reboot, and hit problems.  Bootup got to 'self-checking in 1800 seconds' and 
appeared to hang there.  I did leave it for some considerable time, but it 
didn't move on.  Eventually I used ssh to kill clamd and the boot continued.

I will be away from home for several days, so I need to get this sorted.  I 
presume that it is a mis-configuration somewhere that's causing it.  Can 
someone please advise me what to look for?  Thanks

Anne
