Hi, When using cgroups blkio controller with bio throttling my shell hangs attempting to write limits for md devices. Standard sd devices work as expected but md devices cause the shell to hang on io_wait. For example: echo 9:0 0 > blkio.throttle.read_bps_device Where 9:0 => /dev/md0 I haven't started trying to narrow down when this occured yet, it works fine on 3.2 and I will try out 3.5 etc shortly to see if I can bisect where it stopped working.
