I have just installed SL 5. I'm getting a large number of messages of the form EDAC MC0: UE page 0xbf1 offset 0x0 grain 4096 row 0 labels ":" : i82875p UE Initially they were being sent to /var/log/messages and to all terminal windows. I managed to get the latter to stop. They still go to /var/log/messages at a rate of about one per second. The motherboard is ASUS P4C800 deluxe. I mention that because Googling reveals that this problem was seen with this motherboard a year ago with the 2.6.16 kernel. I cannot find mention of a solution to the problem. Since I do not see where an EDAC module is loaded, I'm guessing that the EDAC code is built into the 2.6.18 kernel in SL 5 and is not loaded separately. Is that correct? I will appreciate suggestions on what's going wrong and how to fix it. Thanks.
