So I updated tumbleweed and now my bluetooth doesn't work. After some investigation, I plan to file a bug report. It seems the firmware worked with kernel 5.14, but now it doesn't work with 5.15. But for now, as long as I boot into the old kernel, I still can use my bluetooth headphones, and this is important for multiple applications. The kernel I want to use is the 2nd kernel in the list, which is 5.14. I want to preserve this kernel so that on future updates, if they have not solved the bug, the 15.4 kernel will be preserved, but the default kernel, which is 5.15, will be replaced by the next kernel update. Is there a way to do this? At one time in the past I expanded the number of kernels that were in the list of available kernels so that I kept like 6 kernels. I don't remember why I did that, and I don't need that many in any case. However, I don't know how to preserve just one kernel, so that that particular kernel won't be erased, but that updates for other kernels will still load and I will be able to try them.
