RouterOS v3.11 got kernel failure using Xeon Processor

We got kernel failure after upgrade to RouterOS v3.11 and got message like this after that

jul/25/2008 21:07:28 system,error,critical System rebooted because of kernel failure

Our router was using Quad Xeon Processor 2.0 Ghz with Intel S5000 motherboard.

Any problem with kernel RouterOS after v3.6 ?
Because our other routers using v3.6 and no problem with their kernel like v3.11.

Did you have multi cpu actived???

Yes, multi cpu was turned on.

you could try to turn it off for now, multi-cpu support is still not universal. some systems have problems with it.

When it becomes stable ?
Because in v3.6, my router has no problem at all and its uptime more than 18 weeks now.

uptime: 18w5d21h44m32s
                  version: "3.6"
              free-memory: 1570800kB
             total-memory: 1945848kB
                      cpu: "Intel(R)"
                cpu-count: 4
            cpu-frequency: 1595MHz

can routerOS v3.11 use same linux kernel with ROS v3.6 ?
