[Kernel-packages] [Bug 1491957] Re: 3.16.0.48 kernel in hyper-v cause hv_netvsc problem
Joseph, it is a live server, but I can test on it, but I am not a linux genius. So I can start is if you show me what I should do exactly from command prompt. (wget? apt?) And one more thing is that I have currently this: Ubuntu 14.04.3 LTS (GNU/Linux 3.16.0-46-generic x86_64) So it is not 14.04.1 as I see the version in the filenames here: http://kernel.ubuntu.com/~jsalisbury/lp1491957/ I can create snapshot from Hyper-V console, so you should not describe how I can revert the changes. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-lts-utopic in Ubuntu. https://bugs.launchpad.net/bugs/1491957 Title: 3.16.0.48 kernel in hyper-v cause hv_netvsc problem Status in linux-lts-utopic package in Ubuntu: In Progress Status in linux-lts-utopic source package in Trusty: In Progress Bug description: I have an Ubuntu 14.04 LTS in Hyper-V.

And because I moved back to previous kernel, I cannot create more logs. But is you really need the "apport-collect 1491957" then maybe I can upgrade again to the new kernel, but after I removed it, now I cannot see it if I try apt upgrade, so in this case please tell me how I can re-update the kernel after I removed it. ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- 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/1491957 Title: 3.16.0.48 kernel in hyper-v cause hv_netvsc problem Status in linux package in Ubuntu: Confirmed Bug description: I have an Ubuntu 14.04 LTS in Hyper-V.
