Updated microcode packages fix HT bug in Intel Skylake and Kaby Lake processorsPublication date: 22 Jul 2017
Affected Mageia releases : 5 , 6
This microcode update fixes a Hyperthreading bug in Intel processor/microcode based on Skylake and Kaby Lake platforms (includes Xeon v5 and v6 and some Pentium models). This defect can, when triggered, cause unpredictable system behavior: it could cause spurious errors, such as application and system misbehavior, data corruption, and possible data loss. Note, in order for the firmware to get loaded early in the boot process, we suggest you recreate the initrd after installing this update. To do so, open up a terminal window, use the command 'su -' to gain root privilegies and then use the command 'dracut -f'. Rebooting the system after that will make the new microcode being used.
