are you running under vmware? i am hitting this with vmware workstation. i'm getting this too. i'm running the latest debian kernel and it just started happening.
i'm using a swap partition and have recreated it a few times / run mkswap. strace swapon -a shows that the syscall swapon('/dev/sdc1', 0) is failing. man 2 swapon says: EINVAL The file path exists, but refers neither to a regular file nor to a block device; or, for swapon(), the indicated path does not contain a valid swap signature or resides on an in-memory file system like tmpfs; or, for swapoff(), path is not currently a swap area.
