1.  Please post the complete output to the command "sh proc cpu sort | ex 0.00". 

2.  3650 & 3850 share the same IOS code.  If the Bug ID describes the 3850 then the bug will also be present with the 3650.  

3.  Raise a TAC Case.  The reason is because Bug IDs (lately) are rarely being updated.  Only TAC can verify if you're hitting this bug or not.

Hello,

on a side note, the bug has this information, so it appears that the 3650 is affected as well:

Further Problem Description:
This can be confirmed by TAC without any impact to the switch.
CSCuz57493 affect 3850/3650 platforms

The workaround is to reload the device, can you do that and check if the problem persists ?
