I can no longer boot my MIPS Creator CI20 with this series (merged
opendingux/for-upstream-timer-v8).

Using screen+ttyUSB, I can see messages stopping at:

...
[  OK  ] Started Cgroup management daemon.
         Starting Regular background program processing daemon...

         Starting System Logging Service...

Nothing really stands out in the error messages. Could you suggest
things to try out to get into a bootable state ?
