Partially because docs.freebsd.org kiding about chunk size it sends (http://www.freebsd.org/cgi/query-pr.cgi?pr=116660) and our firewall really does not like it... I hit CTRL-ALT-ESC when the boot hangs, the result is: KDB: enter: manual escape to debugger [thread pid 18 tid 100008 ] Stopped at kdb_enter+0x32: leave db> trace Tracing pid 18 tid 100008 td 0xc50f4420 kdb_enter(c0a87315,4,1,0,1,...) at kdb_enter+0x32 scgetc(e3c9ec60,c07846fc,c50f4420,c0bfaae8,c50f44b8,...) at scgetc+0x54f sckbdevent(c50f7c00,0,c0c1f060,c50ed680,e3c9ec88,...) at sckbdevent+0x204 kdbmux_intr(c50f7c00,0,c50ed698,e3c9ecb8,c077e12b,...) at kdbmux_intr+0x2b kbdmux_kbd_intr(c50f7c00,1,c0a9c9bd,52,c51e5a1c,...) at kbdmux_kbd_intr+0x25 taskqueue_run(c51e5a00,e3c9ecf8,c0732445,0,0,...) at taskqueue_run+0x10b taskqueue_swi_giant_run(0,0,c0a959fa,40b,c51e59e4,...) at taskqueue_swi_giant_run+0x13 ithread_loop(c51e6170,e3c9ed38,c0a95776,314,c50f3550,...) at ithread_loop+0x1b5 fork_exit(c0732290,c51e6170,e3c9ed38) at fork_exit+0xb8 fork_trampoline() at fork_trampoline+0x8 --- trap 0, eip = 0, esp = 0xe3c9ed70, ebp = 0 --- db> Regards, -- Roman
