Intrepid won't hibernate in many cases

When trying to hibernate, in some cases, I get a lot of message on console that force me to make a hard reset. The message have the for of :

[13138.245117] compcache: Error allocating memory for compressed page:
38089, size=35
[13138.245119] Write-error on swap-device (252:0:304712)

When the message doesn't show up, the resume does work.

The only difference I can notice between the times hibernate works and the one it doesn't is that hibernation fails when I have a running process (in my test, I used tcencode).

I use Intrepid with kernel 2.6.27-7-generic.

I googled this issue but the only thing that I found was this thread :
    http://code.google.com/p/compcache/issues/detail?id=12

I don't know where I can find more information. since I suppose the logs aren't written when trying to hibernate.
