-----------------------------+----------------------------------------------
 For the last month or so, my GTA02 often receives a wake-on-wireless
 interrupt from the ar6000 even though the ar6000 is supposed to be off.
 This wakes up the phone unnecessarily. The interrupts appear in dmesg as
 "ar6000_wow interrupt", and based on those messages it seems that they
 occur in spurts of about 20-30 interrupts with an average of 0.07 seconds
 between each one.

 I'm running the latest kernel right now
 (d9a7be9aab65cd86981d60806041ac11fe514277), but it's been hapenning for a
 while now. I can easily disable this behavior by disabling the request_irq
 call in mach-gta02.c, but I shouldn't have to do that.
