Hello,

I have many oop's during the boot (at least that is what the dmesg outout at the below link says)

https://home.comcast.net/~x14sg1/System ... -grsec-smp
https://home.comcast.net/~x14sg1/config-3.5.0-grsec-smp
https://home.comcast.net/~x14sg1/dmesg
https://home.comcast.net/~x14sg1/vmlinu ... -grsec-smp

They are all similar to this
