I have tried two different fixes for this (#12 and #13).
It won't stop.
At this point I can no longer use raid at all.
If my boot drive was raid 5 I'd be screwed as I could not turn it off at all.
I use raid 1 so I am lucky.

Can someone post a command to FORCE the raid to be clean?
Perhaps a forced immediate sync?
The 'mdadm --wait-clean --scan' only tells mdadm to do it as soon as possible.
It does not work either.

I have resorted to running ">echo 5000 > /proc/sys/dev/raid/speed_limit_max" on boot to gain control of my machine back. It slows the resync to 5mb/sec instead of 120mb/sec. However, with this temp fix I never have a full raid mirror backup.

I use my machine to do real work.
This is beyond unbearable and unthinkable that this bug has no cure yet.
