Is there any reason the amd76x_edac module doesn't appear in the Fedora 10 kernel RPM? As far as I can see it should be being built from the configuration.
We've got an AMD 790X based motherboard which doesn't seem to have any Fedora 10 support for ECC RAM.

According to the kernel Kconfig file it's only available for old 32-bit Athlons, and it is in the i686 kernel(s).
config EDAC_AMD76X tristate "AMD 76x (760, 762, 768)" depends on EDAC_MM_EDAC && PCI && X86_32 help Support for error detection and correction on the AMD 76x series of chipsets used with the Athlon processor.

Thanks. I didn't realise it was only 32 bit athlons only.
Any idea what EDAC modules 64 bit Athlon 64s should use? Under RHEL the k8_edac module provides ECC checking, but this module no longer exists as far as I can tell in Fedora 10.
I seems strange that Fedora doesn't support ECC on AMD systems, but RHEL does!

the reason for that is that k8_edac is not upstream. k8_edac and amd64_edac are available at http://bluesmoke.sf.net/. To explain why: on 64 bit athlons the ECC error reporting is done by MCE events and because of that, k8_edac and amd64_edac need to have access to MCE registers but the developers never managed to convince the mcelog maintainer to share those registers. it's a long (ongoing) story.

The k8_edac module in RHEL5 is there via an out-of-tree patch. I can't recall why, but upstream had issues with the code, so it has yet to be merged into Linus' kernel, thus the reason its not in the Fedora kernel.
CC'ing Aris, who might have a better idea on upstream progress of that code...
