Comment 2 for bug 1788321

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.

UBUNTU GUYS -- PLEASE HELP!
