Hello,
I couldn't reproduce this on a Westmere. Are you sure you're testing a clean compilation? Can you bisect the kernel?
I don't do a make clean normally, but I will do it this time when bisecting,
Sorry, I meant a clean build of the kvm selftests, not the kernel. The kvm selftests makefile is a bit lacking and I've noticed that tests can assert in random places if they aren't built from scratch - ensuring all changed dependencies also get recompiled. Fixing up the makefile is on my todo, but it wasn't very high on it, since 'make clean && make' is fast enough.
also I only use shallow clones so it will also take some time pulling. Also to note, The arch I am using is Haswell, I am not sure if that should make any difference though.
I'm not sure either, and unfortunately I don't have the same hardware as you to try and reproduce.
What would be the difference in CONFIG_* fragments that you both have enabled?
Here is my config file: https://pastebin.com/fCNV2z8c
I checked the differences but nothing interesting stood out. I'm using a defconfig config with a couple extra file system modules tacked on.
