Here are some more test runs on boldore, using different kernels, mostly from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D. The attachment is a tarball containing dmesg output associated with runs of the cpu_offlining script. An overview:
* 4.10.0-38-generic: No hang or misbehavior; verbose dmesg output.
* 4.11.0-041100-generic: No hang or misbehavior; verbose dmesg output.
* 4.12.0-041200-generic: No hang or misbehavior; dmesg output is even
more verbose and includes multiple "error -22" messages.
* 4.13.0-041300-generic: Similar to the above, but dmesg errors are
now "error -19".
* 4.13.16-041316-generic: No system hang or misbehavior; dmesg
output has no errors and is much shorter.
* 4.14.0-041400-generic: Segfault and limited functionality
thereafter; dmesg has multiple "error -19" messages and multiple
general protection fault dumps.
