Comment(by cjb):

 > I think at this point, the firmware (or something) is already
 confused/broken:

 The firmware isn't running.  On the way down in userspace, we *cut power*
 to the 8388 via the EC and /sys/power/wlan-enabled.  (This is a new
 feature in 8.2, #7879.)

 The 3strikes is coincident with that:

 {{{
 [  232.994419] olpc-ec:  running cmd 0x35
 [  233.000236] devpath 1 ep3in 3strikes
 [  233.003973] usb 1-1: USB disconnect, address 3
 }}}

 EC command 0x35 is "put the 8388 into reset".
