David I believe I got the patch(es) you mention in in the stable 4.15.1 kernel: Pull x86/pti updates from Thomas Gleixner: "Another set of melted spectrum related changes" (commit 6304672b7f0a5c010002e63a075160856dc4f88d). Unfortunately, the symptoms I reported remain on at least the i486 and i686. - Matthew
