Can you use addr2line or similar tool to show > us the exact location of the oops? In the meantime, I rebuilt the kernel with vm and slub debugging turned on, but actually nothing really informative came out during dmesg. Anyhow, it still oopsed, but obviously the IP was different. Here's the new oops, with addr2line output below.
