It looks like it freezes the system for the second or two it takes

triggers this almost continuosly every few seconds during compilation.
I've also seen this when working with big files(for example graphic
images in uncompressed formats).
It gets very annoying and I don't remember this happening before
activating the ATA_CAM flag. There was some slowdown with big disk
access, but not a total freeze.
I think ZFS does this all the time, i.e. regardless of underlying device
drivers. Can you test your theory by going to an older kernel and
keeping *everything* else the same?
