I am experiencing a similar issue on another system (at91sam9n12) that
uses Redpine Signal Wireless Driver 1.1.0.  I do not know the root
cause yet,  but it may be related to the Redpine Signals driver.  Will
update this mailing list if the problem is with the redpine driver.
thanks

If this is what I think it is - the redpine signals wifi driver, then I
have no interest in this bug report whatsoever.

Please tell us
 * the exact kernel version, best with local patches
 * the wifi driver used

and what function this really was (0x10100100 isn't really useful).
