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. ** Attachment added: "dmesg outputs from several kernels" https://bugs.launchpad.net/ubuntu/+source/linux-hwe/+bug/1733662/+attachment/5017211/+files/boldore-tests.tgz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1733662 Title: System hang with Linux kernel 4.13, not with 4.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe/+bug/1733662/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
