Which kernel version is this for and can you build linux-intel kernel?

I can't reproduce this error on thud or master that is currently using
4.14.78. I am guessing that this commit should have fixed this:


https://github.com/intel/linux-intel-lts/commit/a971fc44c94b6e20f492a93e3e6e5f1735d8afb8

Do you have a local configuration or a bbappend that is over-riding
kernel srcrev?

Would you be able to bisect and see what is causing the problem?
binutils was upgraded to 2.31 back in July.
