That's because LVM is overzealous about running invalidate_buffers() when
running vgscan (it shouldn't do that). It was never able to invalidate
busy buffers, but now there is a warning when it tries to do so. I would
submit a patch to remove the invalidate_buffers() call from PV_FLUSH, but
since the -ac kernel still has block devices in buffer cache, there is
the _possibility_ of a disconnect between user space and kernel space
w.r.t. snapshot data (which is written from kernel space).
Cheers, Andreas
