Keep in mind that you're running a non-longterm kernel, which means |
7 |
that if there is a known regression or security issue in your kernel, |
8 |
a kernel update to fix it wouldn't be provided upstream. |

If you were running 3.16 or 4.4 you would get these updates. If you |
11 |
plan to stick with a kernel for a very long time you should try to |
12 |
pick one that is designated as a longterm kernel. 3.16.85 was |
13 |
released just a week ago. It obviously doesn't get very frequent |
14 |
updates, but if something important comes along they'll release a fix. |
15 |
I'd have to check the timelines but you might have unmitigated Spectre |
16 |
vulnerabilities in that kernel. |

Also, you mention AMD. If you happen to be using a Ryzen processor |
19 |
there were a number of updates to the kernel to better support it. I |
20 |
forget which kernels have these but if you don't have those patches |
21 |
you'd probably benefit from an upgrade. If you have a pre-Ryzen CPU |
22 |
then that won't matter much. |

I completely agree that you can get away with a longterm kernel and |
25 |
there are a lot of reasons for doing so. I just recommend sticking |
26 |
with one that actually is supported. |
