Re: kexec

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@xxxxxxxxxxxxxxxxxxx list.

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
