akedumpfile. The problem is that after INIT is issued, 2nd kernel starts and makedumpfile fails with the following error message. /proc/vmcore doesn't contain vmcoreinfo. '-x' or '-i' must be specified. makedumpfile Failed. The cause of this problem is that kernel does not call crash_save_vmcoreinfo. When kdump starts by panic or sysrq-trigger, crash_save_vmcoreinfo is called by crash_kexec. But this function is not called when kdump starts by INIT. The Attached patch fixes this. This patch just adds crash_save_vmcoreinfo into machine_kdump_on_init so that crash_save_vmcoreinfo can be called when kdump starts by INIT. I tested this patch with linux-2.6.25-rc9 and I confirmed it worked. Signed-off-by: Takao Indoh Signed-off-by: Tony Luck Z
