"Failed to find cpu0 device node" boot msg Same thing here. Those two lines while using the new 4.1.2-2 kernel package, specifically.Jul 19 11:52:09 lappy kernel: Failed to find cpu0 device node Jul 19 11:52:09 lappy kernel: Unable to detect cache hierarcy from DT for CPU 0Not sure what to make of it, since I could find only a handful of references to this error in relation to people who are using the new kernel (like here on the manjaro forums).Maybe this is something unique to Arch or Arch-based distros, then? Perhaps using the LTS kernel package (3.14.48-1) is good general advice until this problem is further explored, because those errors did not happen when I booted with the LTS kernel.

There are special interrupt(s) in the kernel. This interrupt(s) function calls a soft-lockup counter, it will compare the current time stamp with the specific kernel CPU data structure time information. If it looks like the current time stamp is greater than the defined threshold (in seconds) later as compared to the stored time stamp, it is assumed that the monitoring process or watchdog thread(s) have not executed in a respectable amount of time. Why or how can a CPU soft lock occur? How can a CPU get locked if the kernel is carefully scheduling CPU access? Basical
