G'day all,
I'm baffled.
I'm running 2.6.33.2 and I have several arrays :
brad@srv:~$ cat /proc/mdstat

I've also attached a diff between the 2.6.33.2 and the 2.6.34 configs just in case.
Simply reverting back to 2.6.33.2 makes the problem go away.
Have I done something obviously dumb or not provided the right (or enough) info?
Regards,
Brad
