Known Affected Releases

6.5.3.BASE

Description (partial)

Symptom:
upgrade a device running the 6.5.3 release to a 7.x.x image, then attempt to downgrade from this newer image of 7.x.x back to the 6.5.3 release. One would do this if one hits a showstopper issue in this newer image and then needs to downgrade back to the 6.5.3 release. After the downgrade the EMSD process is constantly crashing. This is seen only in downgrade scenario from 7.x.x to 6.x.x or lower.

Conditions:
This is only seen in eXR platforms and while downgrade from 7.x.x to a 6.x.x release.
