microcode cpu0: update failed for patch_level=0x06000832

I'm trying to install arch in vmware workstation 11.1 as a guest. It's the first boot in archlinux after the install. Grub loads, I press enter and I get the following error:

starting version 219
/dev/sda2: clean ...
/dev/sda4: clean ...
/dev/sda1: clean ...
[2.445664] microcode cpu0: update failed for patch_level=0x06000832
[2.445735] microcode cpu1: update failed for patch_level=0x06000832

I followed the beginner's guide and vmware workstation: 11.1 is set for: 1 processor/2cores, 2.9 gb ram,  80gb hard drive.

Any suggestion on how to get ahead?

Thanks

I don't think that the microcode update will work in virtualized hardware... You should apply microcode updates only on your physical machine.

Pretty sure they apply to my virtualbox vm cleanly.  Need to verify though.

I'm not applying any microcode update. It's arch. I just tried to follow the beginner's instructions

So, how do I disable it? or what do I need to do different during the install?

Thanks

I don't think that error is causing any problems, you could ignore it.  If you want to remove the microcode update (I believe it is not necessary in a VM), merely remove the reference to the microcode image (intel-ucode.img) in your boot loader configuration.  Edit: preserve the reference to vmlinuz-linux

I can't ignore it. The boot stops and it's frozen, dead, nothing...

How do I remove the microcode update? or How can I install arch again and make sure that the microcode update is not enabled?

Thanks

It's strange, that error should not prevent your system to boot. What is your cpu? However, before the system boots, in grub select the archlinux entry (actually it should be already selected) and press 'e', then change the following line

initrd  /intel-ucode.img /initramfs-linux.img

to

initrd /initramfs-linux.img

Finally press 'F10' to boot.

How do I remove the microcode update? or How can I install arch again and make sure that the microcode update is not enabled?

Intel microcode is not installed by default, but it is provided by the package intel-ucode so just don't install that package or use pacman to remove the currently installed one and rebuild grub configuration.

Nope. the last line of grub version 2.02^beta2 says:

initrd /initramfs-linux.img

There is no mention of intel's microcode.

The real CPU is an AMD 8350 with 8 cores (no hyperthread). Could it be related to Kernel 4.0? How can I do enough of a boot to install linux-lts which is still at kernel 3.14?

Thanks

Well, the wiki says

For AMD processors the microcode updates are available in linux-firmware, which is installed as part of the base system

I don't know what to do in this case, sorry.
