The boot script parser causes the kernel to panic (with page fault dereferencing a zero pointer for example) if there is an error in the boot script, instead giving a useful error message.

For example, having an extra new line in the ext2fs module line before --device-master-port triggers this behaviour.

There may be many more such error types in the parser.
