The primary difference +between a standard system boot and a kexec boot is that the hardware +initialization normally performed by the BIOS or firmware (depending on +architecture) is not performed during a kexec boot. This has the effect +of reducing the time required for a reboot. + +Make sure you have selected CONFIG_KEXEC=y when configuring the kernel. +The CONFIG_KEXEC option enables the kexec system call. -- cgit v1.2.3
