I recompiled the Linux 4.9.3 kernel as per your previous instructions and successfully installed it in Ubuntu 22.04.4. However, when using Linux 4.9.3 to start Guest OS, it crashes with the following prompt message. I don't understand why this is happening? Doesn't it support Linux 4.9.3 anymore? But I saw that the submission record on Github only modified the header file, which shouldn't be the case, but I really don't understand why.
