Everybody knows that any kernel module can be blacklisted via GRUB line:
However, not everybody knows the exact name of module to blacklist. And that is the real problem! How to identify it?
For example, during of loading of GRUB I see:
rtlwifi firmware not available
which is quite useless of identification. Neither
nor any other variants worked. How do I figure out the name?
The same thing goes with Bluetooth adapter. It throws:
