Since ECC is said to be essential for server systems both in buisness and science and I do not question this, I was wondering if I can not report ECC errors via a watchdog or UEFI (ACPI?) report to syslog facility on FreeBSD. FreeBSD is supposed to be a server operating system, as far as I know, so I believe there must be something which didn't have revealed itself to me, yet.
If the hardware supports it, such errors should be logged as MCEs (Machine Check Exceptions). I can say for sure it works pretty well with Dell servers, as I had one with failing RAM module, and it reported the corrected ECC errors in dmesg.
Memory ECC errors are logged in to messages and you can decode it by sysutils/mcelog. I did it in the past on one of our Sun Fire X2100 M2 with FreeBSD 8.x.
