+OMS VME58 retry problem

+Several errors in the OMS VME58 driver were found.  All the errors +caused the same problem.  Namely, erroneous retries occurred intermittently when multiple axes were commanded to move on the same controller.  This error occurred because old position data was being passed back from the driver after Done was detected.  The erroneous intermittent retries occurred more often when the Oms setup parameters called for a high frequency -(e.g., 60 Hz) "polling" rate and Oms interrupts were enabled. +(e.g., 60 Hz) "polling" rate and OMS board interrupts were enabled. +

+OMS Stop problem

+A problem with issuing a stop command (via either the STOP or SPMG +field) was found with all OMS boards and all versions of +the OMS device drivers.  The root cause of this problem is a statment +in the OMS manual that is not entirely correct; the AC and VL commands +are not completely queued. +
