Hi Steve, Thanks for the suggestion. We moved to 3.4.2 kernel and observed the same issue, ie System hangs while booting. In 3.4.2 port, we are using mips timers (count & compare - csrc-r4k.c & cevt-r4k.c) as clocksource. The last few prints on the console are : Synchronize counters across 2 CPUs: done. NET: Registered protocol family 16 bio: create slab <bio-0> at 0 Switching to clocksource MIPS As mentioned in my previous post, even with 3.4.2 kernel, the control loops in stop_machine_cpu_stop function. Do you suspect anything here? btw, if we set "clocksource=jiffies" in the bootargs, the system boot goes fine. The issue is observed only during switching from default clocksource to MIPS clocksource. Also, the boot works fine with 'nosmp=1' option & MIPS clocksource. Please suggest on the possible debug approach for this issue. Thanks for your support.
