Since update to 6.9.1 from 6.8.3 powerdown restarts with a parity check and parity check is slow.

Ever since I upgraded from 6.8.3 to 6.9.1 if I shutdown the server with the /usr/local/sbin/powerdown or reboot the server with /usr/local/sbin/powerdown -r when the system reboots it always performs a parity check like it didn't cleanly shutdown.

Also, my Parity check average is 66 MB/s instead of 116 MB/s like it was on 6.8.3.
