I have an application that works fine on 14.04.1 but does not work fine on 14.04.2.

I found a bug report that indicates the newer kernel in 14.04.2 is the source of this issue. Is possible to downgrade the kernel in 14.04.2 from 3.16.0-39 to 3.13.0-43, which was the kernel used in 14.04.1? Or, do I have to remove 14.04.2 and reinstall 14.04.1?

  • I doubt that a user space application can have this kind of issues. What is that application? – Pilot6 May 23 '15 at 20:10
  • Here is were I found the discussion on switch back to the original kernel forums.sonarr.tv/t/native-mono-crashes/4985 – hydro7 May 23 '15 at 20:12
  • It seems that will not solve your issue. In 3.13 kernels there is same problem. And you can't just downgrade to 3.13.0-46, if it was not installed. Just wait till it is fixed, or install 4.0. – Pilot6 May 23 '15 at 20:22
  • And it looks like it is being fixed already. Maybe already fixed. What is your current kernel version? – Pilot6 May 23 '15 at 20:23

Yes, you can switch to 3.13 kernel easily.

  1. Install 3.13 kernel by running

    sudo apt-get install linux-generic
    
  2. Remove all linux-headers and linux-image packages of 3.19 version using synaptic. This will also remove 3.19 meta packages.

  • notice that 14.04.2 comes with linux-generic-lts-utopic which is 3.16.x.x and linux-generic-lts-vivid is 3.19.x.x which can be manually installed ;) – JoKeR May 23 '15 at 20:20
  • I know that. That's why I gave that command. – Pilot6 May 23 '15 at 20:26
  • I just meant you mentioned to remove 3.19 version packages in your answer ;) – JoKeR May 23 '15 at 20:40
  • And this will remove "lts-utopic" too. – Pilot6 May 23 '15 at 20:45
  • yes if they are installed... I mean 3.19 ;) – JoKeR May 23 '15 at 20:53
