What command did you use to watch block_dump?
Even if I switched to Firefox and reduced the HDD writes, iotop shows me often
jbd2/flush and I would like to see if something is wrong.
About your question, I can't help you but maybe it's related to a
daemon/software running in the background.
What distribution are you using? Paste the ouput of "uname -a" and your
/etc/fstab would be a good start.
You can try noatime option, in your fstab and see if it's better.
