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...
