linux new kernal?

[Souranil21 chakraborty]

I have a question is after the release of the newest linux kernal and the distros that are using the kernal are being more unstable? cause i saw some post reagrding the unstable nature of different distros in various different people's computers. though i haven't updated my pop os distro on my computer and also is not noticing any unstable nature with my computer.

many people told different issues with their different distros such are those are listed below:-

1. (Ubuntu) crashing after everytieme rebooting. link:- 

    

2. (pop os) multi monitor setup reacting weird and not showing the desktop in the bottom half part of the screen. link:-

3. (pop os) only gettign 30hz output through the built in thunderbolt port on a dell xps 13. link:-

Some hiccups are expected when upgrading the kernel, however I don't see anything indicating that the problems you listed are due to that... there could be plenty of reasons for people getting these problems independently from each other with no relation to the kernel.

yeah i am not saying that these are all related to the kernal. But i am asking is it happening to many people? and also are these related to new kernal releases seems like these can be related to the drivers also

It's impossible to know just by looking at those posts, you can check distro specific newsletters to see if there are any known problems with an update.

Keep in mind that different distros often use different kernel versions that may or may not receive distro specific updates and patches. As far as I know Ubuntu is typically not using the absolute latest kernel but does sometimes backport fixes and drivers from newer kernels. So the issues may very well be Ubuntu specific (Pop is based on Ubuntu)

Distributions keep at least one (sometimes more) older version of the kernel installed (kernel upgrade won't remove the kernel you are currently running because you need to restart the system to actually run the new kernel, so you'll always have at least two if you don't remove the old one manually later) so if you suspect your problems are caused by the new kernel, you can boot the old one. If you don't dualboot, on some distributions the GRUB (bootloader) menu is hidden and you need to press and hold Shift to get it, but after that you can select the older kernel by going to the Advanced options menu:

Drivers tend to be part of the kernel release. The problems above can be to any reason imagineable. For example some library was changed and people developing e.g. a desktop environment didn't notice that. Also drivers, also kernel, though I doubd the kernel itself would cause that. Some driver inside a kernel - surely.  

Also it may be that during the kernel update some modules (in my case it is often ZFS) are not yet updated to the newest kernel, and as a result they are not being rebuilt. Laptop with some missing modules can for example lose ability to operate the touchpad.

 

Most likely the solution of these problems is in logs.
