I have a test setup whereby each of my test drives has been GEOM labelled and then encrypted with GELI, and the resulting .eli devices thrown into a ZFS raidz1. Upon setting this up, I occasionally get TIMEOUTS on the drives (although these don't seem to create noticable problems). Also, halting the system at this point produces a spew of lock-order reversals. In one rare case the system locked up as it was unable to unmount the pool from the rest of the filesystem.
