Hello.

Could anybody help with kexec. I cannot find some informaton from google.

I try to use kexec for fast boot new kernel but I have error below:

# 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.
