I can confirm this. Before updating to 9.10 I took a snapshot of my root partition. From then on I kept seeing the 'failed: Invalid cross-device link' message and experienced delays of several seconds each time the message was printed during a boot. After reading this thread I removed the snapshot and the problem went away.
