I see this message, "unmount: / is busy" whenever I try to reboot the computer.
Hi RedHat, I have exactly the same problem, but only on my IBM computer's with normal scsi disks. I also have an IBM with serveraid installed and the problem is not there at all. On one Dell server is not there either.

You must have modfied some of your initscripts that cause /proc to be unmounted prematurely and in turn the final shutdown steps are not performed cleanely.
