When kmemcheck kernel support configuredi 1/4 ?we encountered random kernel panic
(sometimes can be booted) during system boot process in our environment. I
have tested the mainline kernel version from v3.0 to v3.11-rc6, they also
have this problem. And the memory limit within 4G also tested.

Here attached the config, the panic screenshot, and the hardware information
about our environment.

Thanks,
