OK, thanks for the explanation. But as we have found out in the mean time, the assumption was wrong to enable it by default for all architectures as some architectures cannot boot a crash dump kernel with their default bootloader but only through kexec. Can we have a follow-up patch to disable crash dump kernels where they're not needed? I mean, not every platform supported by Linux is obviously a x86-based or POWER-based server. Adrian -- .''`.
