NVIDIA 340xx problem with kernel 5.6.6

Hi list members. After having worked fine for a number of kernel upgrades from 5.4 to 5.5 ... , the nvidia-340xx module was not automatically rebuild by kmod during the kernel upgrade to 5.6.6 leaving the system stuck during the boot process. Right now I've uninstalled kernel 5.6.6 and excluded kernel* in /etc/dnf/dnf.conf. I'm using Fedora 31 on an HP pavilion dv5 laptop The nvidia driver has been installed following this: https://rpmfusion.org/Howto/NVIDIA I've attached the log file: "/var/cache/akmods/nvidia-340xx/340.108-1-for-5.6.6-200.fc31.x86_64.failed.log" but the system rejected it with the following message: "The message is larger than the 128 KB maximum size" so I've removed the attachment and re-sent the mail. Can someone kindly help me ? Thanks in advance Angelo
