Hi Giridhara,

http://ark.intel.com/products/64622/Intel-Xeon-Processor-E5-4650-20M-Cache-2_70-GHz-8_00-GTs-Intel-QPI

Show it has only 8 core of CPU. Why are you setting the CONFIG_NR_CPUS=64.
certainly it will have a issue in the kernel.

Hi Anand,

Agree it?s a 8 core processor, but Hyper threading is supported in this CPU. 

Thanks
Giri

That will depend on exactly why you're still running a 2.6.32 kernel from 6 years ago. Remember - the fact it's all the way up to 2.6.32.65 doesn't mean you have all the bugfixes.  It only means you have all the bugfixes that qualified for the -stable side of the fence (which is a small fraction of all the fixes that have happened in the past 6 years).

Hi Valdis,

We were running 2.6.32.60 assuming it's a stable build and my assumption was wrong :(. Should I go ahead with stable 3.18.3 [2015-01-16 ].

Thanks
Giri
