I also have a few tips to check out: - Does /proc/cpuinfo contain the same lines for both CPUs?
Yes. Identical information for both CPUs. Checked the status information in the BIOS setup screens - and the vcore and CPU temperature settings are all nice and correct.
- How the memory is attached to the CPUS? (It should be 2x2x1GB.)
2x1GB on each CPU. In order to test things I also tried it with only 2GB installed (all on CPU0). Same thing. I found the option in top to get it to display the CPU channel now. It seems the problem is tied to CPU 0. Hmm.. Perhaps I should try to physically swap the CPUs on the motherboard and see if the problem moves with the CPU or not...

Enable it in the BIOS and then load the ecc.o module... Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SuSE Linux AG, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126

You don't need ecc.o on Opteron. It's handled by the normal machine check handler. -Andi

If there was a single proper way there wouldn't be any options, no? It really depends on how your motherboard is set up, what revision of the CPU you run, what and how many DIMMs you use and where you put them. Also some kernels assumed that the BIOS would enable the MCE error reporting, which some newer ones don't.
the HDAMB documentation from rioworks offers no guidance at all here, let along Linux specific recommendations.
All the glory details are in the BIOS&Kernel developers guide from the AMD website (but read the Specification update too) If you don't want to go that low level: A reasonable default setting is probably ECC on, scrubber on, chipkill off. -Andi
