You could try to get more logs in this way: First locate the address of the __log_buf symbol inside the kernel: > $ sudo grep __log_buf boot/System.map-5.15.0-130-generic > ffffffff8423a770 b __log_buf In the above it's on x86, so you'd need to do the same with the ARM Trisquel installation. Then you need to boot the Trisquel installation, and find the reset button on your rockpro64. Press the reset button and in u-boot interrupt the boot with ctrl+c. Once in u-boot you can try to see the kernel logs with the 'md' u-boot command: you need to give it the __log_buf address (here maybe it's 0x8423a770 or 0xffffffff8423a770 I'm not sure) and then it will print the 'dmesg' content. And you can then press enter multiple times and it will repeat the last command and this way give you the full log. The log is then not very convenient to read as you get 8 or 16 characters per line but it's better than nothing at all. Also note that I also have a rockpro64 but I use it with Guix. Denis.
