Sorry for not being clear. I'm talking about the mainline kernel from
kernel.org:
drivers/devfreq/Makefile:obj-$(CONFIG_ARM_TEGRA_DEVFREQ) += tegra-devfreq.o

Booting a mainline kernel with tegra-devfreq enabled will hang my machine
during bootup when I use the u-boot from R21.4 (which I believe is the
latest provided by NVIDIA).
