It is very difficult to know for sure whether you need a microcode update or not, but it is not safe at all to just ignore them.You might not notice their effect and have precious data silently corrupted, or an important program silently misbehave.Or you could experience one of those unexplainable and infrequent software issues (such as kernel oops, application segfaults) or hardware issues (including sudden reboots and hangs).The BIOS (or EFI) updates the CPU microcode during boot, however most of the time either the motherboard vendor won't issue frequent BIOS/EFI updates, or the user won't install such updates.For these reasons, the If this is the first time you install the microcode update packages in one specific system (computer), it is recommended that you check beforehand for BIOS/UEFI updates from the system vendor and apply those prior to installing the microcode update packages.
This information lets the user know whether the driver is providing a benefit (otherwise they can uninstall it).
If the guest tries to update the CPU microcode, it will fail and show an error message similar to: CPU0: update failed (for patch_level=0x6000624) To work around this, configure the guest to not install CPU microcode updates; for example, uninstall the microcode_ctl package Red Hat Enterprise Linux of Fedora guests.
Good Morning Linux Experts, While booting my machine - I see the following message scroll along on my screen. :-) HTH -- Mark Nullus in verba Nil illigitimi carborundum Nyeh nananana :-p however I will say that for some reason your answer did not show on the nntp server and still does not for "me" anyway.
Processors from Intel and AMD may need updates to their microcode to operate correctly.
These updates fix bugs/errata that can cause anything from incorrect processing, to code and data corruption, and system lockups.
