Description (partial)

Symptom:
A Nexus 3000, 3100, or 3500 device fails to boot up after an NX-OS software upgrade from an NX-OS software release prior to 7.0(3)I7(7) or 9.2(4) to an NX-OS software release in the 9.3(x) train (such as 9.3(1), 9.3(2), 9.3(3), etc.) using a compact image (an NX-OS binary image file that has had its filesize reduced through the NX-OS Compact Image Procedure). The device will be stuck in a boot loop and will output a message similar to the following on the console while attempting to boot up:

 Image valid
MD5Sum mismatch
File does not exist, boot failed.
