https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1317811 ** Tags removed: verification-needed-trusty ** Tags added: verification-done-trusty -- 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/1275879 Title: Kernel panic Status in linux package in Ubuntu: Fix Committed Status in linux source package in Trusty: Fix Committed Status in linux source package in Utopic: Fix Committed Status in linux source package in Vivid: Fix Committed Bug description: SRU Justification Impact: Under certain workloads a BUG in the xen-netfront driver is getting triggered. Fix: Remove the offending BUG, and a related BUG which would have also been triggered by the same conditions. Test Case: This bug has only been seen under certain workloads involving haproxy and has proved challenging to reproduce. The fix has been verified by an affected user, with the BUG replaced by a WARN to ensure that the conditions which would have triggered the bug were actually encountered. Regression Potential: The fix has been verified and acked upstream. Removing the BUGs will not affect cases which were not crashing previously, and cases which were crashing can't really be made much worse. --- I run ubuntu servers 13.04, 13.10, and 14.04 on the AWS cloud. Whenever I install haproxy and nginx on the same server, after hitting it for a while, a kernel panic is caused. However, the kernel panic does not show up in ubuntu 12.04. The kernel panic is pasted at the end of the attachment.
