A timing issue sounds likely, as nothing much has changed in the mesh
driver (or the rest of the SCSI code AFAIK) lately.  If you set
mesh_debug_targets back to 0 but still have MESH_DBG defined, it won't
print all that debugging info but it will still record all the log
information (which is a relatively lightweight thing to do), and if
you get the target aborting, it will print the log.
