Some specs of your computer would help here:

does your computer have a first generation Xeon Phi (x100 series) PCIe adapter? for those you'd need the MPSS 3.8.2 stack. For the Xeon Phi x200 (aka Knight's Landing) you do NOT need the MPSS stack.

hmmm why not install the supplied package (mpss-modules-2.6.32-696.el6.x86_64-3.8.2-1.x86_64) ?  this will set up a "weak link" that will load the module in the 696.6.3.el6 kernel without any issues.

Also. check that the module can be loaded

$ modprobe mic

I had installed mpss with mentioned kernel modules. But that gives me an error. In the 'readme.txt' Intel mentions to rebuild the module. Right now modprobe mic command runs and does not give any output.

what error did it produce?

OK, now check that the module is loaded and start the mpss daemon:

$ lsmod | grep mic
$ service mpss start

then check that the card can be found:

$ micinfo

Please post the output, or post the output of 'micdebug.sh' here.
