I've been simply living with this issue. I can reproduce it by rsyncing very
large files to a btrfs volume. My entire desktop will freeze for up to three
minutes and no amount of nice/ionice can temper this.
Once I've finished the rsync certain apps will periodically hang (Firefox in
particular). This behavior goes away after a reboot.
I'm running kernel version 3.0.
