I don't have a reproducer other than install the kernel and wait 24h as that's how long it took for some systems to panic...
From a very quick look, those kernels are mainline kernels, unfortunately all my hosts are LXC hosts using unprivileged containers with overlayfs, so I need kernels with the Ubuntu patchset applied for them to be usable.
For now, I'll go test the current -proposed kernel on my least critical system, see if I can get that one to panic.
