I have reinstalled SuSE now, and I apologise as I was only partially correct. I do get errors, but they are slightly different from RH. They appear to be saying the same thing, though. Every 30 seconds I get:
Aug 11 10:37:06 terra kernel: Northbridge status 9405c00000000a13 Aug 11 10:37:06 terra kernel: ECC syndrome bits b Aug 11 10:37:06 terra kernel: extended error ecc error Aug 11 10:37:06 terra kernel: link number 0 Aug 11 10:37:06 terra kernel: corrected ecc error Aug 11 10:37:06 terra kernel: error address valid Aug 11 10:37:06 terra kernel: error enable Aug 11 10:37:06 terra kernel: previous error lost Aug 11 10:37:06 terra kernel: error address 00000000003e4710 Aug 11 10:37:36 terra kernel: Northbridge status 9405c00000000813 Aug 11 10:37:36 terra kernel: ECC syndrome bits b Aug 11 10:37:36 terra kernel: extended error ecc error Aug 11 10:37:36 terra kernel: link number 0 Aug 11 10:37:36 terra kernel: corrected ecc error Aug 11 10:37:36 terra kernel: error address valid Aug 11 10:37:36 terra kernel: error enable Aug 11 10:37:36 terra kernel: previous error lost Aug 11 10:37:36 terra kernel: error address 00000000003c4220
These suggest it's just reporting ECC corrections. Why would it do this exactly every 30 seconds? (or is that just the reporting interval?)

thanks for the help,
