I think this is likely an audio issue; either you held down a key when
turning on an XO which open firmware from playing its startup sound, or you
turned the volume control for the startup chime all the way down.
http://dev.laptop.org/ticket/11082 states that the os41 software build
supposedly fixes this. It should be run with the latest firmware, which is
Since you are getting into Linux you should not have to open the XO to
reflash via the #11089 fix again. You should be able to just break into OFW
by using the ESC key when the startup sound plays, insert a USB stick with
Q4B08, and type "flash u:\q4b08.rom" with external and battery power
