Today I have Ubuntu 14.04 LTS OS and kernel 3.13.0-83 in my 64 bit laptop. With this kernel version I have still same problem of ''Kernel panic ...'' announcements and required reboot actions as with earlier kernel 3.13.xx versions.

I am waiting for online update to Ubuntu 16.04 LTS to this same laptop.

Does this online update to Ubuntu 16.04 make AUTOMATICALLY also change of new kernel to 4.4.6 ? Or should I change kernel somehow separately ? How stable this kernel 4.4.6 is ? Brgds Kauko Peltonen

Ubuntu 16.04 will be shipped with kernel 4.4.

If you upgrade from 14.04 to 16.04, you will get kernel 4.4 installed.

Ubuntu kernel numbers do not match exactly the mainline versions. It will be 4.4.0-xx, that will be based on the latest 4.4.x mainline version.

You can install kernel 4.4 to Ubuntu 14.04 without upgrading to 16.04 by running in terminal

sudo apt-get install linux-generic-lts-xenial

Regarding "how stable is 4.4.6", it can't be answered as it will be based on opinions.

  • What is your Ubuntu version? To get output in English, run the command with prefix LANG=C, like LANG=C sudo apt-get......

  • Run the updated command, and you will get kernel 4.4. But that may cause some trouble with video drivers. But you still will be able to boot from 3.13 kernel using grub.

Yes, the distribution upgrade will also update the kernel. However, keep in mind that the upgrade from 14.04 to 16.04, will be offered automatically as soon as 16.04.01 is released and not from the first 16.04 release.
