The problem began with the update to a 5.9 kernel and has been consistent with each successive kernel release. The machine is a dual boot with another version of Linux and the other version does not display the same problem, only the Fedora install. Last working (and still working) is kernel 5.8.18. The machine will start to boot but the last message on the screen in the boot sequence is:
random 7 urandom warning(s) missed due to reatelimiting.

From some net searching, I though it might be the bios setting for the SSD drive. It was set as IDE (options werre IDE, RAID or AHCI) and have tried AHCI but it is the same problem. Search results indicated it should not be RAID so have not tried that option.
Until I am able to resolve this problem have been deleting the 5.9 kernels and installing and testing to see if they boot.
