Rob seemed to be aware of this when I brought it up the other day: my 3.17 kernel seems to boot fine, brings up the secondaries, and I can look at /proc/interrupts or /proc/cpuinfo and see 4 CPUs, all taking interrupts. However, as soon as i run dmesg, i get ~50 lines of output and then the console hangs solid. Attaching GDB reveals that the kernel is still running, i.e., cpu_do_idle() etc, so it might just be the UART being in a funny state -- Ard.
