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
Please suggest on the possible debug approach for this issue.
Thanks for your support.
