When the system is up, try to unmount /proc.  If it fails, find out what
is preventing the successful unmounting like this: 'fuser -vm /proc'

That command should tell you what processes are "in" that fs.

When the system is up, does 'free' report any swap space available? 
Look at /etc/fstab, and make sure the device file for your swap is
correct.  If so, run:
# swapoff <swapdev>
# mkswap <swapdev>
# swapon <swapdev>

Otherwise, fix fstab.
