RHBA-2011:0768 - edac-utils bug fix and enhancement update

Synopsis

edac-utils bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated edac-utils packages that fix one bug and add one enhancement are now available for Red Hat Enterprise 6.

Description

EDAC is the current set of drivers in the Linux kernel that handles detection of ECC errors from memory controllers for most chipsets on the x86, AMD64, and Intel 64 architectures. The user-space component consists of an initscript which ensures that EDAC drivers and DIMM labels are loaded at system startup, as well as a library and utility for reporting current error counts from the EDAC sysfs files.

This update fixes the following bug:

  • Previously, the edac-utils initscript did not use the standard error codes of other initscripts because several mandatory actions were missing. This update implements the initscript actions "condrestart", "try-restart", "force-reload" and sets the return values for each action accordingly. Now, the initscript uses the standard error code. (BZ#632665)

This update also adds the following enhancement:

  • This update extends the maximum number of channels from 2 to 6, in order to allow it to work with some designs that have 4 channels on FB-DIMM motherboards, e.g. the ones with Intel 7300 chipset. By default, this update identifies the motherboard via BIOS DMI board information. If not available, it will fallback to use DMI system information. (BZ#640113)

Note: the improvements from upstream version 0.16 are now added to edac-utils, including new motherboard labels, an option to delay the motherboard write labels, and a better parser to retrieve memory and vendor information from the system.

All EDAC users are advised to upgrade to these updated packages, which fix this bug and add this enhancement.

Solution

Before applying this update, make sure all previously-released errata relevant to your system have been applied.
