mcelog bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated mcelog packages that fix three bugs and add two enhancements are now
available for Red Hat Enterprise Linux 6.

Description

The mcelog packages provide the mcelog daemon to collect and decode Machine
Check Exception data on AMD64 and Intel 64 platforms.

This update fixes the following bugs:

• Prior to this update, the mcelog README file contained references to
  nonexistent directories. This update removes these references and updates the
  file. (BZ#728265)
  
• Prior to this update, the mcelog daemon wrongly displayed an error that a
  certain microarchitecture was not supported even if the CPU was supported if
  mcelog was run on Intel CPUs only with architectural decoding enabled. This
  update removes this message. (BZ#769363)
  
• Prior to this update, a cron job tried to install regardless whether a system
  was supported or not. As a result, the mcelog daemon displayed the message "No
  such device" if mcelog was installed on unsupported systems. This update
  prevents the cron job from installing on unsupported processors. (BZ#784091)
  

This update also adds the following enhancements:

• Prior to this update, the mcelog daemon displayed the error "mcelog read: No
  such device" when running the unsupported AMD Family 16 microarchitecture or
  higher. This update adds a check to mcelog to determine what AMD processor
  family is used. If needed, the new message "CPU is unsupported" is displayed.
  (BZ#746785)
  
• Prior to this update, The cron file for mcelog did not use the "--supported"
  option. As a consequence, the "--supported" option did not correctly check
  whether the mcelog daemon worked. This update adds the "--supported" option to
  the crontab file and removes two redundant strings. (BZ#795508)
  

All users of mcelog are advised to upgrade to these updated mcelog packages,
which fix these bugs and add these enhancements.
