Do you happen to know if this bug was present in ubuntu 11.10, kernel
versions 3.0.0-15-server or 3.0.0-16-server ?

I saw failures to assemble RAID6 arrays after unclean shutdowns on both of
these, just in test environments.  If it happens again I'll send mdadm
--examine output. I just tried to replicate it and failed :-(
