It does not hang anymore, but now reliably crashes when trying to use
the interface:

Waiting for DAD to complete for statically configured addresses...
Starting dhcpcd.
panic: kernel diagnostic assertion "ipq != NULL" failed: file "../../../../net/if.c", line 862 

Seems like the per-cpu if_queue is NULL, how could that happen?
Interface is awge0, backtrace:
