I am using ssh to remotely access some machines. These machines have a custom kernel installed (based on the 2.6.28 source). However, whenever I try to reboot the machines using
sudo reboot, the system uses kexec and loads the 2.6.28-19-generic kernel, which is also intalled on the machine.
So how can I specify which kernel image to load after reboot?
EDIT: I have ubuntu 9.04 installed on the machine, with grub 1.something. The custom kernel is based on the 2.6.28 source with the name being 188.8.131.52-custom-1.1. Two other kernels are installed on the machine 2.6.28-19-generic and 2.6.28-6-386. I have checked that after calling reboot, the machine does not actually reboot but uses kexec to load the 19-generic kernel, even if the current kernel was the custom one.
