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?
