On a unrelated site note, I have a case where I can trigger a
FH_ERROR at this line 100% reliably. Not on Linux though..
While being associated to a 5GHz BSS doing a scan chan by chan
(instead of all at once) is enough to trigger it. A workaround
is too not send probe requests for 2GHz channels at 1Mbps (CCK
flag) but at 6Mbps instead.

Maybe this bug report [1] is related too?
