I found the problems, which i can not reliably reproduce, happened when i ran into kdump kernel boot failure (yet not every time.) What puzzled me was why only /sbin/kexec was affected. I can not explain what caused it (otherwise i would be able to reproduce it) and do not know where my finger should point to. ;) The good news is since i fixed the kernel boot problem it has not happened any more. The distros probably can add a check against zero-sized kexec in /etc/init.d/kdump script though.
