I was having the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED partmgr.sys BSOD problem on both my desktop and laptop after the Anniversary Update, but I seemed to have solved it.
Grab
USBDeview and find the Kindle Device in the list and uninstall it from the system (right click in the list and uninstall). I had to use uninstall twice before it was removed from the list completely but then I could plug in my Kindle Paperwhite with no more BSODs!
I really hope this helps others!
