Description of problem:
SELinux is preventing plymouthd from 'map' accesses on the chr_file /dev/fb0.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that plymouthd should be allowed map access on the fb0 chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'plymouthd' --raw | audit2allow -M my-plymouthd
# semodule -X 300 -i my-plymouthd.pp
