 Doing an rsync to my USB drive (with wapbl, etc.), after freshly 
 formatting it eventually yielded:
 
 panic: kernel diagnostic assertion "de->td_node == node" failed: file 
 "/nbu/source/netbsd/src/sys/fs/tmpfs/tmpfs_vnops.c", line 657

 Given that I wasn't doing anything with tmpfs at the time (or 
 rather...rsync wasn't...maybe some other process was, since that's 
 /tmp), it seems like a strange backtrace.
 
 Maybe there's more than one issue going on here?
