(x86 architecture) I generally try few things. - Specify earlyprintk= parameter for second kernel and see if control is reaching to second kernel. - Otherwise specify --console-serial parameter on "kexec -l" commandline and it should display a message "I am in purgatory" on serial console. This will just mean that control has reached at least till purgatory. - If that also does not work, then most likely first kernel itself got stuck somewhere and we need to put some printks in first kernel to find out what's wrong.
