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.
