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

  To mount /proc at boot you need an /etc/fstab line like:

  In the meantime, mount /proc /proc -t proc

Please stand by while rebooting the system...

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.
