Hi Ben, Thanks for trying the test kernel out. Its great to hear that your analysis was correct, and it was "x86: Increase brk randomness entropy for 64-bit systems" causing the issues.
I am still deciding what to do. You see, I came across this mailing list thread: https://lore.kernel.org/all/202411210628.ECF1B494D7@keescook/T/ where Kees asked to revert from stable tree, but in the end, Greg K-H decided that it should stay in the kernel and QEMU should be fixed instead. Let me establish the blast radius of this first, and figure out what needs fixing and what doesn't. But I think we should follow Debian and fix QEMU. I will write back soon.
