Kernel Package Compatibilitypackage compatibility

Unlike the Windows' ABI upward compatibility policy on Windows, on in Linux, certain versions of Linux kernel packages are generally not compatible with higher kernel versions. Because new features and improvements are added as kernel versions go upto each kernel version, installing an older version versions of a kernel package can packages may cause compatibility issues. Of course, in some cases, kernel packages are compatible with higher kernel versions. For example, if a kernel package for kernel version 5.15.0 works with kernel version 5.16.0, this is because kernel version 5.16.0 includes all the features and improvements of kernel version 5.15.0.However, BSR does not support backward compatibility for higher kernels unless otherwise specified, which means that you must install a dedicated BSR package for a Installation may not be possible, or even if installed, serious problems such as kernel panic may occur during operation.

Likewise, bsr does not support compatibility of lower version packages with higher kernels unless specifically specified. That is, you must install the bsr package for your specific kernel version.
