With Linus’ master branch from today, and Greg’s char-misc-linus merged
(Merge: 807b93e995d1 546cf3ef9c92), the regression is still there.

I am now building a Linux kernel image with the two commits touching
`bus-fixup.c` reverted.

Do you want me to open a separate bug report for that, or continue
debugging in the existing report [1], which is currently marked as resolved?

Do you have Kaby Lake devices sitting around for testing?

Kind regards,

Paul
