Is Linux Kernel 5.* now considered to be stable?

Several days ago, i upgraded my Kernel to 5.15.2-2. Initially it seemed fine, but after waking up from sleep, my wireless Microsoft mouse was almost unusable. it was very sticky that many many wheeling just made it move a little bit up or down the scrolling bar.

It was just the same issue i encountered before years ago when I was first trying Kernel 5. i didn’t dig too much, but it seems that it was a Kernel bug yet didn’t fixed. Once again i simply downgrade to 4.19.

That’s it.

Manjaro is slightly behind what is currently posted here:

(yes … there are multiple 5.X kernels that are ‘stable’ and even LTS … though 5.15 is rather young)
