This problem will occur without a suspend / resume cycle. This problem appeared recently, within the last month or two months of kernel updates. I think the next step in debugging would be to test reliability against previous kernel versions. some relevant dmesg: keyboard: can't emulate rawmode for keycode 240 iwl3945 0000:0c:00.0: BSM uCode verification failed at addr 0x00003800+0 (of 900), is 0xffffffff, s/b 0xf802020 iwl3945 0000:0c:00.0: Unable to set up bootstrap uCode: -5 iwl3945 0000:0c:00.0: MAC is in deep sleep!.
