UPDATE: The name of this thread has changed to show that it has evolved into a kindle debricking solution that uses a new kindle fastboot for windows tool. This thread started as a search for a solution to the problem of a kindle dropping out of fastboot mode when you change the host PC from windows (for MfgTool) to linux (for fastboot).
