Both revisions are bad. r255488 gives panics of at least 3 kinds. r256624 doesn't give panics but is virtually unresponsive - I have to wait for over minute in some cases for simple commands to complete (ls, df, ps, top, ssh, etc.) So since I cannot send back anything certain from r256624, I decided to revert to r255488, where at least I can get textdumps.
