This looks strange, maybe you need to clone torvalds tree, and just add
that tree as a remote?

With current backtrace, it already points us to exact where the problem is.

Even if I have the access to the VM, I still need to download the source

And I doubt if I built the kernel using different config/compiler, it
would no longer reproduce the bug.
