Topic
An updated mcelog package that fixes various bugs is now available.
Description
mcelog is a daemon that collects and decodes Machine Check Exception data
on AMD64 and Intel 64 machines.
This update includes the following bug fixes:
- The mcelog service did not check whether another instance of mcelog was
running, which could result in multiple mcelog service instances on a
single system. This could result in lost or over-reported Machine Check
Exceptions. mcelog now detects whether another instance is already
running, preventing multiple instances from being launched on a single
system simultaneously. (BZ#614874)
- When a Machine Check Error occurs, a message indicating that the issue
is not a software problem is output to the console. This incorrectly
implies that a hardware problem exists. The message has now been corrected
to indicate that a Hardware Event has occurred, instead. (BZ#646568)
- No configuration file was provided for mcelog, preventing users from
configuring mcelog daemon and its actions. A default configuration file
(/etc/mcelog/mcelog.conf), which can be used to modify the behavior of
mcelog at runtime, is now provided. (BZ#647066)
- Support for future Intel processors has been added to mcelog, enabling
mcelog to decode Machine Check Exceptions for these processors when they
become available. (BZ#664016)
- The default mcelog configuration file contained references to files
that did not exist in the default package installation. This caused mcelog
to attempt to execute files that did not exist. The mcelog configuration
file has been corrected. Note that this bug was reported and corrected
during development, and was not seen in production systems in the field.
(BZ#682753)
All users of mcelog are advised to upgrade to this updated mcelog package,
which resolves these issues.
