Dear Guoging,
I think now that this is not an issue for md. I've driven a system into that situation again and have clear indication, that this is a problem of the member block device driver.
With md0 in the described errornous state (md0_raid6 busy looping, echo idle > .../sync_action blocked, no progress in mdstat) and md1 operating normally:
root:deadbird:/scratch/local/# for f in /sys/devices/virtual/block/md?/md/rd*/block/inflight;do echo $f: $(cat $f);done
