[Kernel-packages] [Bug 1491957] Re: 3.16.0.48 kernel in hyper-v cause hv_netvsc problem

2015-09-05 Thread Lőrinc
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.

2015-09-03 Thread Lőrinc
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.

[Kernel-packages] [Bug 1491957] [NEW] 3.16.0.48 kernel in hyper-v cause hv_netvsc problem

2015-09-03 Thread Lőrinc
Public bug reported:

I have an Ubuntu 14.04 LTS in Hyper-V. It works well. Today I apt
upgrade the kernel from 3.16.0.46 to 3.16.0.48 and after reboot, I have
network connection problems, and have a lot of error message on screen
like the above ones.
