[CentOS] CentOS won't shutdown ... or do anything else

I started to have problems similar to ones described in the past on 
this list but could not find any kind of resolution. I did an 
lsmod, a mount command, and for fun, did an strace on shutdown to 
see where it is hanging, and an ltrace as well.

Any thoughts?
