I'm building a x86_64 2.6.22 kernel with the following options set: CONFIG_KEXEC=y CONFIG_CRASH_DUMP=y CONFIG_RELOCATABLE=y CONFIG_PHYSICAL_START=0x200000 If I try to load the kernel with the following I get: ./kexec --args-linux -p '--command-line=ro root=LABEL=/1 rhgb quiet irqpoll maxcpus=1' --initrd=/boot/initrd-2.6.22.19.img /boot/vmlinuz-2.6.22.19 ./kexec: unrecognized option `--args-linux' kexec-tools-testing 20080318-rc released 18th March 2008 Usage: kexec [OPTION]... [kernel] ... Cannot load /boot/vmlinuz-2.6.22.19 Now if I remove --args-linux kexec successfully loads the panic kernel but when I trigger a crash it just loads the kernel and doesn't actually perform a kdump. So this proves the relocatable nature of the kernel is working right? Its just not passing args as would be needed to trigger a crash dump? If I use the same commandline above (--args-linux included) with a RHEL5U1 kernel kexec will load the panic kernel without problems and kdump will work when I enduce a crash. So long story short: is there some fix that went in upstream after 2.6.22 was released that would enable kexec to load a relocatable x86_64 kernel with the --args-linux option? Nothing stands out to me but I could easily be overlooking something... Mike
