Boot hangs while adding swap

Boot process hangs after reaching the following line:

Adding 5853176k swap on /dev/mapper/mch-swap_1. Priority:-1 extents:1 across:5853176k

Using knoppix 6.2 as LiveCD, and mounting the partitions, I got the following:

# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).

Is there any problem in fstab?
Please help me. I could not reinstall the server.
