Unload and disable the atm kernel module. 1. Run the following commands to unload the atm kernel module: # modprobe -r atm 2>/dev/null # rmmod can 2>/dev/null 2. Perform the following to disable the atm kernel module: Create a file ending in .conf with install can /bin/false in the /etc/modprobe.d/ directory Example: # printf '\n%s\n' "install atm /bin/false" >> /etc/modprobe.d/60-atm.conf Create a file ending in .conf with blacklist atm in the /etc/modprobe.d/ directory Example: # printf '\n%s\n' "blacklist atm" >> /etc/modprobe.d/60-atm.conf
