Hi, I'm so sorry for not giving you more details, I'm a freshman here, but I'll try to do better in the future. I will give the answers under each of the questions .

As for network, it did work well without my patch. >Is the missing DHCP connectivity the only difference you see with kdbus? Acctually, I cannot connet to the device by "adb".

(in case of git: which commit?) systemd v219 commit: d736e4f3e76daca4ab1b1fc444737e5ee20a27cd >Did you pass --enable-kdbus to systemd? Yes , I did. >What upstream kernel version do you use? 3.10.33, we back-ported the kdbus to our kernel. >Any obscure messages in the system-log that you didn't see before? From dmesg , I can see that the "systemd" process calls kdbus_bus_broadcast() endlessly, and the condition " if (conn_dst->id == kmsg->msg.src_id)" is always true. It seems that when booting, the "systemd " process enters a dead loop by sending some signal to the source connection. So , systemd cannot boot any service , including network. Thanks!
