I have trouble with some SD Cards so I enabled debug output from SD driver with sd_debug=on in /boot/config.txt. I have looked with journalctl and checked the files in /var/log and in /tmp but cannot find any debug information.

Where to find the debug output from SD driver?

The correct syntax to enable this is dtparam=sd_debug=on. After putting this in config.txt, debug information from the SD driver should show up in dmesg.
