Up to date. [tmiller at office04]$uname -r 2.6.32-279.14.1.el6.x86_64 Then I tried the command the web page has (I see my error during bootup) [root at office04 Documents]# /etc/init.d/mcelogd start [root at office04 Documents]# /etc/init.d/mcelogd status Checking for mcelog mcelog is stopped [tmiller at office04]$ls /dev/mc* /dev/mcelog so the device does exist [root at office04 Documents]# locate edac_mci_amd returned nothing, but I don't know if it should or not. I was reading the MAN page, and noticed "See mcelog --help for a list of valid CPUs." so I tried it, and it lists: Valid CPUs: generic p6old core2 k8 p4 dunnington xeon74xx xeon7400 xeon5500 xeon5200 xeon5000 xeon5100 xeon3100 xeon3200 core_i7 core_i5 core_i3 nehalem westmere xeon71xx xeon7100 tulsa intel xeon75xx xeon7500 xeon7200 xeon7100 sandybridge sandybridge-ep All the CPUs I recognize in there are Intel, though I don't know all the nicknames. cat /proc/cpuinfo on my system shows (only first of two cores copied) processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 35 model name : Dual Core AMD Opteron(tm) Processor 180 stepping : 2 cpu MHz : 1000.000 cache size : 1024 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 ht syscall nx mmxext fxsr_opt lm 3dnowext 3dnow rep_good pni lahf_lm cmp_legacy bogomips : 2009.40 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp Not the latest and greatest, and old enough I expected it to be supported by now. Any clues in all this? Ted Miller
