--------------------------------------------------------------------------------SELinux is preventing /usr/sbin/ptp4l from module_request access on the system labeled kernel_t.*****  Plugin catchall_boolean (89.3 confidence) suggests   ******************If you want to allow domain to kernel load modules
Then you must tell SELinux about this by enabling the 'domain_kernel_load_modules' boolean.Do
setsebool -P domain_kernel_load_modules 1*****  Plugin catchall (11.6 confidence) suggests   **************************If you believe that ptp4l should be allowed module_request access on system labeled kernel_t 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 'ptp4l' --raw | audit2allow -M my-ptp4l
# semodule -X 300 -i my-ptp4l.pp
