Kernel: vanilla 3.15-rc5
kexec: latest git (21.05.2014)

I can load the zImage + dtb from u-boot, but invoking kexec prints
following data and nothing happens after "Bye!":

# kexec -d -f --dtb=/mnt/boot/am335x-evmsk.dtb /mnt/boot/zImage
kernel: 0xb5eab008 kernel_size: 0x2036c
kexec_load: entry = 0x80008000 flags = 0x280000
nr_segments = 2
segment[0].buf   = 0xb5eab008
segment[0].bufsz = 0x43d328
segment[0].mem   = 0x80008000
segment[0].memsz = 0x43e000
segment[1].buf   = 0x29008
segment[1].bufsz = 0x7e89
segment[1].mem   = 0x810f6000
segment[1].memsz = 0x8000
Starting new kernel
Bye!

u-boot output for the same kernel+dtb:

Wang, what hardware do you use?
