 I generated a lot of traffic with 3 XOs placed only some centimeters apart
 from the test unit. This is the wispy spectrum read (close to the XO
 position).

 {{{
 Channel Grade (%)       Duty Cycle      Average Floor(dBm)      Average
 Peak (dBm)
 11      9,759895        32,81314        -64,14802       -56,36956
 }}}

 It was not enough to make the XO reset (but enough to cause me a headache
 ;-). He could actually associate to the AP in one of the attempts (the AP
 is in the same channel - 11).

 The failing modes are the same as reported in this ticket's sibling
 (#8667). At least for this test, high contention did not change anything.
