May i assume you did swapoff before?

You change hostname inbetween or this is just a typo?

Wow. Any of the errors above prevents swap partition from being used.
How did you manage to see anything in /proc/swaps?
I suggest you do:
swapoff /dev/hda6
badblocks /dev/hda6
Alternatively, you can try
dd if=/dev/zero of=/dev/hda6; mkswap /dev/hda6
Look for "SWAP-SPACE" (old swap) or "SWAPSPACE2" (the new one).
Just to make sure you've initialized the partition properly.
Than turn it on: swapon /dev/hda6; tail /var/log/syslog

Oops, you've sent, is pretty useless without decoding. Read
Documentation/oops-tracing.txt from the kernel source tree.
