Before, I had problems installing the a200 intel wifi/bluetooth driver which I didn't manage to install properly (I had downloaded it but couldnt use it - I didn't get it running). Then I installed instead blueman, dkms etc and got an internal error message. I de installed all that and the internal error message is also gone, but I still get this message when booting.
In the progress, I also edited via vim that "compress gzip" but that didn't help.
I also had entered rtbth in /etc/modules over vim but I am not sure whether I did that correctly.
Nonetheless, I de installed blueman, blueman manager and dkms but I am still left with that error message shown above, that had not been there before I started to fix my bluetooth problems.
Maybe you can help? (BTW, kernel is 5.4)
