I'm suffering from excessive hd activity in Ubuntu 12.04.

If I check with iotop, I see (and hear) jbd2 flashing every second. I know that jbd2 is just the sync process for ext4, so that's a cause, not an effect.

Eclipse juno is running, but if I stop eclipse, it does not solve the problem.

I'm using the following kernel: 3.7.4-030704-generic

Here's the output from ps -ef
