  I have a [Firmware Bug]: TSC_DEADLINE disabled due to Errata; please 

update microcode to version: 0x22 (or later).  This diagnostic is 

displayed during boot and is recorded in /var/log/dmesg . How does one 

obtain the necessary microcode?



For Ubuntu and presumably other .deb based distributions:



Just install intel-microcode with sudo apt-get install intel-microcode 

and reboot.



End quote.



What is the equivalent EL command and from which repository does the 

command get the "intel-microcode"?    The CPU is an Intel I7 in a HP 

Zbook laptop from several years ago.



Thanks for any information.
