** Description changed: - Reloading the Hyper-V LIS modules can sometime result in a kernel panic. + Reloading the Hyper-V LIS modules can sometime result in a kernel panic. Technical details: a hypercall can return “invalid alignment” error if the input parameter spans a page boundary. Updated LIS code handles properly the error without returning bug(). We've triaged this issue internally and the following 2 patches have been created. Please include them in 14.10 (Utopic Unicorn) daily builds and let us know when we can test. https://lkml.org/lkml/2014/8/27/725 https://lkml.org/lkml/2014/8/28/649 + + === + break-fix: - 45d727cee9e200f5b351528b9fb063b69cf702c8 + break-fix: - b29ef3546aecb253a5552b198cef23750d56e1e4 ** Tags added: kernel-bug-break-fix ** Also affects: linux (Ubuntu Vivid) Importance: Critical Assignee: Andy Whitcroft (apw) Status: In Progress ** Also affects: linux-lts-utopic (Ubuntu Vivid) Importance: Critical Status: Confirmed ** Also affects: linux (Ubuntu Utopic) Importance: Undecided Status: New ** Also affects: linux-lts-utopic (Ubuntu Utopic) Importance: Undecided Status: New ** Changed in: linux (Ubuntu Utopic) Assignee: (unassigned) => Andy Whitcroft (apw) ** Changed in: linux (Ubuntu Utopic) Importance: Undecided => Critical ** Changed in: linux-lts-utopic (Ubuntu Utopic) Status: New => Confirmed ** Also affects: linux (Ubuntu Trusty) Importance: Undecided Status: New ** Also affects: linux-lts-utopic (Ubuntu Trusty) Importance: Undecided Status: New ** Changed in: linux-lts-utopic (Ubuntu Vivid) Importance: Critical => Undecided ** Changed in: linux-lts-utopic (Ubuntu) Status: Confirmed => Invalid ** Changed in: linux-lts-utopic (Ubuntu Utopic) Status: Confirmed => Invalid ** Changed in: linux-lts-utopic (Ubuntu Trusty) Status: New => Confirmed ** Changed in: linux (Ubuntu Utopic) Status: New => In Progress -- 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/1366120 Title: [Hyper-V] reloading LIS Hyper-V modules can result in a kernel panic on Ubuntu 14.10 Status in linux package in Ubuntu: In Progress Status in linux-lts-utopic package in Ubuntu: Invalid Status in linux source package in Trusty: New Status in linux-lts-utopic source package in Trusty: Confirmed Status in linux source package in Utopic: In Progress Status in linux-lts-utopic source package in Utopic: Invalid Status in linux source package in Vivid: In Progress Status in linux-lts-utopic source package in Vivid: Invalid Bug description: Reloading the Hyper-V LIS modules can sometime result in a kernel panic.
