We have MAXv servo motors moving slightly when we push the reset button

on our mvme2307 processor. It actually appears that the move happens

when the system goes down instead of on restart. We see this only when

we push the reset button on the card, not when we type "exit" at the

EPICS prompt or do a power down and power up. We're running RTEMS 4.9.5,

EPICS 3.14.12, motor record 6.52. We did not see this with an older

kernel, which was RTEMS 4.9.2, EPICS 3.14.9, motor record 6.2. We used

to see similar behavior on power cycles but this was fixed using an APS

Servo Transition card with the MAXv. I'd be interested in hearing of any

similar experiences.
