[arch-general] After updating mkinitcpio generates a image without modules

Hi, after the last grub update (with kernel 3,9,7) when the pacman runs to build the new boot images, pacman output many errors with modules not being found. The log is attached. I tried to chroot from a livecd and tried to reinstall all the packages, tried to downgrade the kernel and nothing reverted the problem. I cannot figured out why the modules are not being found... Anyone can help me with this? Thanks in advance. --- Eduardo M. Machado
