-A technical report on TKN15.4 is under way and will be available at:
-http://www.tkn.tu-berlin.de/publications/reports.jsp
+Known Issues:
+- resetting the MAC during operation (via MLME_RESET) has not been tested
+- if initial beacon Tx timestamp is invalid, then coordinator can hang
+- frame pending flags are (need to be) always set in the ACK headers
+- transmitting coordinator realignment frames has not been tested
+- using an incoming and outgoing superframe at the same time has not been tested
+- during an ongoing CSMA-CA transmission incoming frames are ignored
+- on a beacon-enabled PAN: if the device cannot find the beacon the DATA frame
+ is not transmitted (but it should be transmitted using unslotted CSMA-CA, see
+ Sect. 7.5.6.1 "Transmission")
