[erlang-questions] Driver load problem on Mac OS Lion

[cao xu]

I got the stack info from core file when the VM crashed:

(gdb) up
#1  0x000000001c0c77c1 in erts_sys_main_thread () at sys.c:2905
2905		res = select(erts_darwin_main_thread_pipe[0] + 1, &readfds, NULL, NULL, NULL);
(gdb) up
#2  0x000000001bfe5bc4 in erl_start (argc=12, argv=0x7fff6bbcb5a8)
    at erl_init.c:1483
1483	    erts_sys_main_thread(); /* May or may not return! */
(gdb) up
#3  0x6c61636f6c2f7273 in ?? ()
(gdb) 


and after I turned off the SMP, the driver worked again. Does that mean it have something to do with the SMP support?
