I haven't yet done as much experimentation as Andreas Pflug has, but I can confirm I'm also running into this bug with Xen 4.4.1.

In order to support ZFS, we upgraded a backups server with a new, ECC motherboard. We're running CentOS 6 with ZFS on Linux, recently patched. Now, I want to enable EDAC so we can check for memory errors (and maybe PCI errors as well) but so far, repeatedly pounding on the Google hasn't yielded exactly what I need to do to enable EDAC. One howto was covering PCI and edac, but "modprobe edac_mc" didn't work. Here's some information below, H...

Hello, I upgraded to CentOS 5.1 and everything went smoothly (Thanks for the awesome work!). But after rebooting, I get the following error: EDAC MC: Ver: 2.0.1 Nov 30 2007 EDAC e7xxx: error reporting device not found:vendor 8086 device 0x2541 (broken BIOS?)

Package: xen-hypervisor-4.4-amd64 Version: 4.4.1-9+deb8u3 Debian 8.2 installed on a supermicro H8SGL Board, AMD 6128 with 4x4GB ECC RAM. When booting the plain kernel (stock Jessie 3.16 or backport 4.1 or 4.3), both memory controllers (mc0 and mc1) appear under /sys/devices/system/edac/mc with two csrow* each as expected. Same happens, when booted with Xen 4.1.4-3+deb7u1. When booted with Xen 4.4.1, only mc1 with two RAM modules is visible, although all 16GB RAM is available in the OS (xl info).

I've got a production system running CentOS 4 that was rock solid until I upgraded from 2.6.9-55 to 2.6.9-78.0.13 (now running 2.6.9-89.0.11). The system now crashes intermittently after a few weeks. I finally caught the panic message : EDAC MC0: INTERNAL ERROR: channel-b out of range (4 >= 4) Kernel panic - not syncing: MC0: Uncorrected Error Looking at the kernel changelog, I see that EDAC support was added for the Intel 5000 chipset in 2.6.9-68.20.EL which this server runs. I'm trying to determine if this is a potential mem...
