I solved this bug (and also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1724657) by inserting intel-ucode.img (taken from recent arch linux iso) as first initrd into grub.cfg. This updates the microcode very early in the boot process. And this way I can use the live iso without having to install to hard drive and install additional packages and so on.
