Backport commits from master that fix boot failure on some intel machines. I have only boot tested this in a VM. Functional testing for v4.14 is out of my scope as patches differ only on a trivial conflict from v4.19, where I discovered/debugged the issue. While testing v4.14 stable on affected nodes would require porting some other [local] patches, which is out of my timelimit for the backport. Hopefully, that's fine.
