That one hung much like the others, with the system responding only to very basic commands (mostly bash internals), although the dmesg output continued further after the kernel bug message. Here's the dmesg output:

This test attempts to take all the CPU cores offline except one, then brings them back online again. This test ran successfully on boldore with previous releases, but with 17.10, the system sometimes (about one in four runs) hangs. Reverting to Ubuntu 16.04.3, I found no problems; but when I upgraded the 16.04.3 installation to linux- image-4.13.0-16-generic, the problem appeared again, so I'm confident this is a problem with the kernel. I'm attaching two files, dmesg- output-4.10.txt and dmesg-output-4.13.txt, which show the dmesg output that appears when running the cpu_offlining test with 4.10.0-38 and 4.13.0-16 kernels, respectively; the system hung on the 4.13 run. (I was running "dmesg -w" in a second SSH login; the files are cut-and- pasted from that.) I initiated this bug report from an Ubuntu 16.04.3 installation running a 4.10 kernel; but as I said, this applies to the 4.13 kernel.
