I have seen this as well, no problem on 2.4 + md (raid5) + lvm2,
about every night on 2.6.2

I believe it is another stacking problem, since there is no problem with
using only one of md and lvm2, but i have no idea how to get
more details on this. I also am an ext3 only user so i have no idea if
other fs are affected.
