That's correct. On 4.0.5:

root at wandboard-solo:~# kexec -d -l /tmp/zImage --dtb
/tmp/imx6dl-wandboard.dtb --command-line="console=ttymxc0,115200
earlyprintk root=/dev/mmcblk0p2 rootwait rw"
my_load:667: do
kernel: 0x75dd1008 kernel_size: 0x5664c8
kexec_load: entry = 0x10008000 flags = 0x280000
nr_segments = 2
segment[0].buf   = 0x75dd1008
segment[0].bufsz = 0x5664c8
segment[0].mem   = 0x10008000
segment[0].memsz = 0x567000
segment[1].buf   = 0x10ab008
segment[1].bufsz = 0x6ba7
segment[1].mem   = 0x1159b000
segment[1].memsz = 0x7000

Applying fee3fd4fd2ad136b into 4.0.5 then kexec works fine.

Should we send fee3fd4fd2ad136b to stable?

Thanks
