That's a hardware cursor, it always blinks. That doesn't mean anything. However, you might try serial console to get a bit more diagnostic. Also, please try (if you still use VGA) kexec --console-vga --debug -p /boot/vmlinux .... That gives a bit more diagnostics in purgatory code to see where the system hangs. However, not sure if that also works when booting the crashkernel. Can you try a normal kexec (with -l) first and see if that works in your configuration? Bernhard
