[solved] AMD Ucode not loading on boot

Its being called twice during the early hooks stage of udev.
i have already googled and found I needed to have installed the AMD Ucode package. I have version 2012.1.17-3 but it is being ignored.

Im getting the error

[unix time stamp i assume] microcode: failed to load file amd-ucode/microcode_amd.bin

twice after a long pause.

How do  I fix it?

Re: [solved] AMD Ucode not loading on boot

Are you including the microcode module in your initramfs? You really shouldn't be...

Re: [solved] AMD Ucode not loading on boot

I have put microcode in there as per instructions, but the word microcode was not in mkinitcpio.conf when I installed the system and started seeing the message. I think I added it on instructions in one of the 2 threads or an arch wiki page on the subject. I'll remove it.

The thing is I HAVE the amd-ucode package installed,  and i'm STILL getting the message and associated delay on boot. So I'm looking for how I inform it I have installed it?

By adding the firmware file to the initramfs.

DO NOT DO THIS

There is nothing to be gained by loading microcode firmware from the initramfs. It will be automatically loaded from userspace once root is mounted and udev starts up.
