Updated mcelog packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
The mcelog packages contain a daemon that collects and decodes Machine Check Exception (MCE) data on AMD64 and Intel 64 machines.
- Previously, mcelog packages installed a cron job to report the status of mce logs, which conflicted with running the mclogd service as default mode. Consequently, mcelog competed with the cron job and did not collect complete data. With this update, cron job is not installed in case mcelogd is running, thus fixing this bug.
- Due to a bug in mcelog packages, the AMD Family 15 architecture was not supported. The bug has been fixed and mcelog now supports AMD Family 15 as expected.
- Previously, support for extended logging was enabled by default in mcelog packages. Consequently, on systems with processors without support for extended logging, the mcelog service terminated unexpectedly with the following message:mcelog: Cannot open /dev/cpu/0/msr to set imc_log: Permission deniedWith this update, extended logging is disabled by default in mcelog packages, and the mcelog service no longer crashes in the aforementioned scenario.
Users of mcelog are advised to upgrade to these updated packages, which fix these bugs and add these enhancements.
