Comment(by werner):
Unload/reset would most likely stop the trouble, but that may just be
because the driver would of course reset the WLAN module. My current
plan is to just observe but otherwise ignore that bug for now and put
everything on the Linux SDIO stack instead. Then we'll see if the
problem persists.
Regarding the USB crash: seems that this is caused by the accelerometer
driver trying to get a mutex while interrupts are off and isn't related
to the WLAN problem. I think Andy has a patch that gets rid of all those
mutex uses in the driver, so it should solve that specific issue.
