When this happened, I just looked at the broken-out patches in -mm, which
ones touch the md subsystem, found your patch, reverse-applied it, and
this stopped happening.

It seemed to be 100% reproducible - happened on every boot of FC6 system,
so it was probably triggered by some raid/lvm command executed from init
scripts after boot, but I didn't examine it further.

As soon as I get to the machine where this happens, I will try to narrow
it down to the exact userspace command that triggers it and will let you
know (probably this evening).
