@aabadie, @haukepetersen currently not has the time to test this. Since I know that you also have some xbee shields: Can you test please?

Tried to build the tests/driver_xbee and got a build failure:

sys/net/gnrc/link_layer/netdev/gnrc_netdev.c:128:5: error: implicit declaration of function 'gnrc_netif_add' [-Werror=implicit-function-declaration]
     gnrc_netif_add(thread_getpid());
     ^~~~~~~~~~~~~~

Tried to build the examples/gnrc_networking application (very optimistic) and got a kernel panic (with and without Xbee module loaded, so might not be related):

Fixed tests/driver_xbee. Can you build examples/gnrc_networking with -DDEBUG_ASSERT_VERBOSE set in CFLAGS and report which line is failing, please?

Now it builds but ends up after in a kernel panic:

That is not a kernel panic, but again a failed assertion. It would be really helpful if you would compile with CFLAGS=-DDEBUG_ASSERT_VERBOSE, because that would give you file and line of the failed assertion ;-)

@aabadie last commit should fix it. Tested with tests/drivers_xbee on nucleo144-f746 vs examples/default on samr21-xpro in various configurations (different channels, PAN IDs, address lengths etc.).

Tested with arduino-zero, works. The Murdock error seems unrelated.

ACK

Yes, that should be fixed with #7414 and #7462 (@aabadie do you maybe have time to review that or the ability to poke @kYc0o about that?).
