You have been subscribed to a public bug: On a Dell Poweredge 720, Kubuntu 13.10 x64, LInux Kernel 3.11.0-14-generic, when setting /etc/sysctl.conf: kernel.sched_autogroup_enabled=0 Kernel fails to boot. This error is 100% reproducible and when I comment out that line in sysctl.conf everything works fine. The machine is 2x Xeon E2670 with 64GB of RAM, I've attached lspci output and also dmesg output during a normal boot.
It starts failing when it detects hard drives, right after it detected ixgbe network driver and when systemd starts to launch programs. If I boot it in safe mode with that option set to 0 and then choose resume in the menu, everything works fine. Apparently when systemd starts something that conflicts with the hard drive detection when autogroup_enabled=0. I've attached screen shots from the KVM. Please let me know if you need any other information. ** Affects: linux (Ubuntu) Importance: Low Status: Incomplete -- Ubuntu 13.10 x64 kernel 3.11.0-14-generic crash https://bugs.launchpad.net/bugs/1261744 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
