#1 - Use your Linux install, Windows will not connect to the serial port in time to get what we need.

#2 - a dummy run, after the Kindle has completed its boot and started the <whatever> it is doing -
I.E: So that diddling with minicom's setup isn't sending to the Kindle something that might otherwise do something (good or bad)

Got all the options on minicom set so that it is working?
Save that as the default configuration.
Now in the future you can start minicom with that configuration and skip it sending anything by:

Code:

minicom -o

Enable the capture to file feature.
minicom is running you will be seeing the serial output
Re-boot the Kindle (Linux will not drop the serial connection like Windows would)
Let the Kindle run through its full power-on boot sequence until you reach the above point.
That will give the full set of u-boot messages, initramfs system messages, and kindle start up messages into the capture file.
turn off the capture to file
save the capture file.
Done with Kindle for now
gzip the capture file and attach to your next post (must use the "advanced" editor here, manage attachments box is below the text box for the post).

I'll go through the capture file, an quote back the lines of interest and a translation of what they mean.

THEN we can decide what needs to be done.
