Do you have this in cmdline? resume= [SWSUSP] Specify the partition device for software suspend Format: {/dev/<dev> | PARTUUID=<uuid> | <int>:<int> | <hex>} > I don't know how to test kexec.) You boot with something like this: crashkernel=512M-2G:128M,2G-64G:256M,64G-:512M Check dmesg to see whether it managed to reserve memory. Then you do: # kexec --noefi -l bzImage --initrd=initrd.img --reuse-cmdline # kexec -e That last one loads it. Anyway, something like that. I have this in my notes saying it worked at some point. -- Regards/Gruss, Boris. SUSE Linux GmbH, GF: Felix Imendörffer, Jane Smithard, Graham Norton, HRB 21284 (AG Nürnberg) --
