[SOLVED]Loading microcode takes too long

Hi,

After upgrading kernel to 3.7.7-1, loading microcode takes about 1 minute for each CPU - there is 4 CPU.

dmesg | grep microcode

uname -a
Linux dem 3.7.7-1-ARCH #1 SMP PREEMPT Mon Feb 11 20:20:58 EET 2013 x86_64 GNU/Linux

Although intel-ucode is installed, microcode is not updated. If I unload then load microcode module, it is updated.

sudo udevadm control --log-priority=debug
sudo modprobe -r microcode
sudo modprobe -v microcode
insmod /lib/modules/3.7.7-1-ARCH/kernel/arch/x86/kernel/microcode.ko.gz

After this commands, related outputs from dmesg

Could you help me to solve this problem?

Loading microcode from the initramfs is a braindead idea. Do not do this. Your firmware requests are timing out since you haven't included the the files on the initramfs which is what causes your delays.

Thank you @falconindy. I removed microcode from MODULES of mkinitcpio.conf, regenerate initramfs and reboot. Now everything is how it should be.

While I was using kernels which are older than 3.7.7-1, why did such problem not happen?
