We should rate-limit correctable error reporting so it's not overwhelming. At the same time, I'm *also* interested in the cause of these errors, in case there's a Linux defect or a hardware erratum that we can work around. Do you have a bug report with any more details, e.g., a dmesg log and "sudo lspci -vv" output? Bjorn
