Gumstix recently shipped a number of Overo Air and Overo Fire COMs with defective wireless modules.  While the wifi portion of the module worked properly, the Bluetooth portion did not.

COMs containing the defective modules will have the following message in the boot log:

Starting Bluetooth subsystem:
Initialization timed out.

 If you have not done so already, please contact support@gumstix.comThis e-mail address is being protected from spam bots, you need JavaScript enabled to view it for warranty coverage.
