Already there :) https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d47924417319e3b6a728c0b690f183e75bc2a702 Tagged for stable. Thanks, tglx -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1733662 Title: System hang with Linux kernel due to mainline commit 24247aeeabe Status in linux package in Ubuntu: In Progress Status in linux-hwe package in Ubuntu: Confirmed Status in linux source package in Artful: In Progress Status in linux-hwe source package in Artful: Confirmed Status in linux source package in Bionic: In Progress Status in linux-hwe source package in Bionic: Confirmed Bug description: In doing Ubuntu 17.10 regression testing, we've encountered one computer (boldore, a Cisco UCS C240 M4 [VIC]), that hangs about one in four times when running our cpu_offlining test. 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.
