I guess I should have mentioned that it was a workaround, but
not a fix.  It turns out that it is not a good call.


The IOC hung at iocInit() after we tried to add the eighth
motor controller cards in the crate running RTEMS-mvme2307.
Further tests showed that,  as a wokaround,one clock tick of delay is
needed between the end of the scaler_init_record()
and before it entered the oms_init_record().  At this point, it seems
that the bug  might not be  even RTEMS related.
rtems_task_wake_after(0) works fine.


We were able to  load eight motor cards in one crate running 3.13.x vxWorks.
I guess a better question is :did anyone load eight OMS58 motor cards
in one crate running 3.14.x /vxWorks ?  We do not have the updated version
of vxWorks for the mvme2307 to test 3.14.x.
The final test I did is based on the EPICS 3.14.5 /RTEMS, and SynApp 3.14.5.
I do not have enough time to try 3.14.6 since I have to turn in
the eight motor cards for operations.


Regards,
Kate
