On further, further investigation, it looks like according to the mcelog install guide at http://www.mcelog.org/installation.html, I could "roll my own" for 32-bit CentOS 6: "For bad page offlining you will need a 2.6.33+ kernel or a 2.6.32 kernel with the soft offlining capability backported (like RHEL6 or SLES11-SP1)" "The kernel has to have CONFIG_X86_MCE enabled. For 32bit kernels you need at least a 2.6,30 kernel." The current kernel I am running is 2.6.32-358.23.2, but I can't tell whether it has CONFIG_X86_MCE enabled. How can I find this out? Thanks, -G.
