Sorry, silly question, but did you try as root? kexec load tries to put the knew kernel on memory and after that tries a syscall to kexec_load to finish with a kexec_reboot, since it handles with mem and syscalls maybe just as a root you will run it properly Also have that kexec@lists.infradead.org list.

# kexec -l /boot/vmlinuz-3.12.0-rc1+ --initrd=/boot/initramfs-3.12.0-rc1+.img --command-line="$(cat /proc/cmdline)" kexec_load failed: Operation not permitted entry = 0x24eff5790 flags = 3e0000 nr_segments = 3 segment[0].buf = 0x7fd169783210 segment[0].bufsz = 505250 segment[0].mem = 0x24d000000 segment[0].memsz = 1413000 segment[1].buf = 0xbc3770 segment[1].bufsz = 4310 segment[1].mem = 0x24efef000 segment[1].memsz = 5000 segment[2].buf = 0xbba650 segment[2].bufsz = 90e0 segment[2].mem = 0x24eff5000 segment[2].memsz = b000
KEXEC option in the config is enabled.
How can I decid this problem?
