This is a BeagleBone Black board Revision B6. Running OpenBSD 5.6-current as of 15 November 2014.
When using net/tor: Tor v0.2.5.10 (git-42b42605f8d8eac2) running on OpenBSD with Libevent 1.4.14b-stable, OpenSSL LibreSSL 2.1 and Zlib 1.2.3. I can use exit nodes to access external sites like https://check.torproject.org. But accessing Hidden Services causes a core dump: Program received signal SIGBUS, Bus error. 0x0010e518 in siphash24 () (gdb) bt #0 0x0010e518 in siphash24 () #1 0x00103568 in strmap_set () #2 0x00045bf8 in rend_client_cancel_descriptor_fetches () #3 0x00045f40 in rend_client_refetch_v2_renddesc () #4 0x000bd3cc in connection_ap_handshake_rewrite_and_attach () #5 0x000be6e4 in connection_edge_process_inbuf () #6 0x000b7f70 in connection_handle_read () #7 0x0002b750 in process_signal () #8 0x4481f0d4 in event_base_loop (base=0xb7978, flags=0) at /usr/src/lib/libevent/event.c:350 #9 0x000286a0 in do_main_loop () #10 0x000294d4 in tor_main () #11 0x00026cc0 in _start () #12 0x00000000 in ??
