Running RHEL 3.0 x86_64 U6 (2.4.21-37.Elsmp) I have searched, logged a call with HP and Redhat support and have turned up nothing. HP says I have memory problems, Redhat says it's a known non-critical error. I am not sure if I am chasing after the correct problem but all six of my AMD64 HP XW9300 (based off Tyan Thunder K8WE?) with anywhere between 4-16Gb RAM and two Opteron CPU's get the following errors : Nov 10 17:18:46 node4 kernel: CPU 0: Silent Northbridge MCE Nov 10 17:18:46 node4 kernel: Northbridge status 94044100:ac080a13 Nov 10 17:18:46 node4 kernel: Error chipkill ecc error Nov 10 17:18:46 node4 kernel: ECC error syndrome ac08 Nov 10 17:18:46 node4 kernel: bus error local node response, request didn't time out Nov 10 17:18:46 node4 kernel: generic read Nov 10 17:18:46 node4 kernel: memory access, level generic Nov 10 17:18:46 node4 kernel: link number 0 Nov 10 17:18:46 node4 kernel: dram scrub error Nov 10 17:18:46 node4 kernel: corrected ecc error Nov 10 17:18:46 node4 kernel: previous error lost Nov 10 17:18:46 node4 kernel: NB error address 000000000126dd40 Nov 14 19:14:16 node4 kernel: CPU 0: Silent Northbridge MCE Nov 14 19:14:16 node4 kernel: Northbridge status a6000001:0005001b Nov 14 19:14:16 node4 kernel: Error gart error Nov 14 19:14:16 node4 kernel: GART TLB error generic level generic Nov 14 19:14:16 node4 kernel: err cpu1 Nov 14 19:14:16 node4 kernel: processor context corrupt Nov 14 19:14:16 node4 kernel: error uncorrected Nov 14 19:14:16 node4 kernel: previous error lost Nov 14 19:14:16 node4 kernel: NB error address 00000000dffe0038 Five of the computers have between 1-30 references to these error messages in the past 3 weeks. One computer has over 30,000 instances of these error messages. I am getting the majority of these messages on computers with >4Gb RAM but I have had the messages on computers with only 4GB RAM. The main reason I am focusing on these messages is that the computers have crashed numerous times since being put online. The computer with 30K instances of the error message has crashed about 1-2 times per week. I am running the latest BIOS. I can not turn on diskdump since they have Nvidia SATA controllers (not support by diskdump) and netdump has not produced anything since during the kernel crash no data was written ( network driver went down? ). Has anyone else seen these messages or have any idea how to identify the problem? Could my crashes be due to Northbridge errors or am I barking up the wrong tree.
