This is a stock Debian kernel. The Debian package name is linux-image-3.11-2-amd64, and the package version is 3.11.10-1. It used to be the current kernel in Debian testing (jessie) but is now one level back. The current testing kernel is a 3.12 kernel, but I can't even get that one to boot. The kernel I'm using is available for download on snapshot.debian.org, which is how I got my current copy of it. This is a binary kernel image package of course, not a source package. The corresponding Debian kernel source package would be linux-source-3.11, version 3.11.10-1, which should also be available on snapshot.debian.org. (Though it contains kernel source, this package is still classified as a "binary" package, as far as the Debian package management system is concerned; so you have to look for it on snapshot.debian.org as a binary package, and you have to be root to install it.) > > Can you resend the /proc/cpuinfo contents *for the kernel with the mismatch, > while the mismatch is happening* just to make triple sure I don't look at > the wrong one/forward the wrong one by mistake? Yes, I'll do that; but I can't do it right now. I've varied processors one and three offline, and it has made my previously unstable system stable. I'm in the middle of doing something long-running on it right now, and once that is finished, I can vary those processors online again. I can even reboot if necessary. But not right now. I have to wait for the long-running process to finish first. -- .''`.
