This is a bit of a weird one ... Attempting to reproduce and fix this bug: https://bugzilla.kernel.org/show_bug.cgi?id=219166 which involves booting a qemu VM with the kernel and observing a fairly rare, but reproducible hang, I'm able to reproduce this reasonably often if I boot the Fedora-built (ie. Koji) kernel. However when I copy /boot/config-6.11.<blah> to .config in the kernel git tree, 'make olddefconfig', build and install it locally, then run the test, it never seems to reproduce. Same config, and I'm even using the same upstream git tag. I'm building it on Fedora Rawhide (same as Koji), so GCC and the rest of the toolchain should be very close. My question is, what are other differences between the Fedora-built kernel and a locally built kernel apart from config (the same), version (the same), and toolchain (nearly the same)? Fedora has a downstream patch set called 'patch-6.11-redhat.patch'. It's not clear where this comes from, but I don't think it touches any code that should affect my test. Other ideas welcome here as I'm out of ideas right now ...
