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@xxxxxxxxx> 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...
