If you get different backtraces on reboots even you only modified things that do not have to do with the problem, it's probably that and related to: http://bugzilla.kernel.org/show_bug.cgi?id=10339 You might want to try the latest kernel or the patch posted there.

Thank you for the update. I have checked the bug and unfortunately its not the same issue. Things work absolutely fine, when I'm running on AC power. It even displays the exact battery (and charging) status to me. It messes up when suddenly AC power gets disconnected and switches to battery mode (The time when I get Oops). The system is still usable after switching to battery mode and I still get correct battery stats until its completely discharged. However most of the commands like kill, poweroff, java doesn't work after the Oops. BTW there is one similarity with the referenced bug. If I boot the computer without AC Power, it gives the same Oops and stops during booting itself. I shall try the latest kernel once and shall update you.

Find the latest dmesg along with the Oops: Ok. Maybe best is you document the backtraces/oopses with kernel versions at bugzilla.kernel.org and add dmesg and acpidump. It seems your machine notifies OS that the C-state table changed. AFAIK this is rare and there might be a general bug in the cpuidle layer which I do not know well. Best you add Venkatesh and Shaohua Li <shaohua.li@intel.com> to CC of the bug. While the backtrace shows a lot, cpuidle IMO is missing a general debug option like in the cpufreq layer. I couldn't find a single printk in the whole cpuidle/{cpuidle,sysfs}.c files, even on error paths. Also in the cpuidle specific parts of drivers/acpi/processor_idle.c some debug printks may help for future bug reports. It is very hard to guess what happened...
