Hi, I am using a USB serial cable and want to see the kernel logs on the console, and towards that have the below line in /etc/default/grub console=ttyUSB0,115200 console=tty0 Hardware: Intel compute stick OS : ubuntu 18.04 kernel : 4.18.0-18 Driver : pl2303 I do not see the kernel logs, and it drops to a dracut shell because the root is encrypted. I am however able to write to the /dev/ttyUSB0 device, and am able to see the output in minicom at the other end, which means that the requisite driver is loaded in initramfs. dracut:/# echo 'hello' > /dev/ttyUSB0 Not sure what I am missing here. Please help. Not sure if this is the correct mailing list. Would linux-console be a more appropriate list? Regards, Shiv
