 Any error is
 fatal on non-raw tape; when possible the driver will have retried
 the operation which failed several times before reporting the error.

-.BR "tj%d: lost interrupt" .
+.Pp
+.It tj%d: lost interrupt.

 A tape operation did not complete
 within a reasonable time, most likely because the tape was taken
 off-line during rewind or lost vacuum.  The controller should, but does not,
 give an interrupt in these cases.  The device will be made available
 again after this message, but any current open reference to the device
 will return an error as the operation in progress aborts.
