Comment 3 for bug 1551790

I have this problem as well but my colleague does not.
I use Intel fake-raid and he uses pure Linux soft-raid.
I don't know why he doesn't have the problem - looking at the scripts in rc6 everyone using raid >1 should be experiencing this bug regardless of fake vs soft.

I think a work-around is to add a ln -s ../init.d/mdadm S50mdadm link under rc6.d
This should make '../init.d/mdadm stop' run after S40umountfs
It is my understanding that everything in rc6 is passed 'stop' and the K's & S's are ignored for this runlevel *except* the alphabetical ordering still matters (which is why it has to be S50 not K50 to run after the unmount.)
