Since the release of Rocky Linux 9, some installations on x86-64 platforms have failed with a kernel panic. In most cases, this is due to the CPU's incompatibility with Rocky Linux 9. This procedure will verify CPU compatibility before installation.


  1. Obtain a boot image of Rocky Linux 8, Fedora, or others.

  2. Boot this live image on the machine where you want the installation of Rocky Linux 9 to be.

  3. After the boot completes, open a terminal window and run this procedure:

    /lib64/ --help | grep x86-64

    You should receive output similar to this:

    This program interpreter self-identifies as: /lib64/
    x86-64-v2 (supported, searched)

    This output indicates the minimum required x86-64 version (v2). Installation can continue in this case. If "(supported, searched)" is missing next to the "x86-64-v2" entry, then your CPU is not compatible with Rocky Linux 9.x. If the test shows that your installation can continue and it also shows x86-64-v3 and x86-64-v4 as "(supported, searched)", your CPU is well supported for 9.x and future versions.
