Debian Serial Console Issue
by ZapDragon from LinuxQuestions.org on (#6JM40)
Hello!
I have a unique setup here and I've spent easily 6 months trying to figure out where my problem is.
I Have a QNAP TS-h973AX and I have setup Debian 12.0, with kernel 6.1.0-17 back in July.
It was days of trying to get the serial console to work.
The issue is that serial console works perfectly till I boot Debian.
This is regardless of if its the installer or my currently running environment.
At very random and frequent times, the serial console will completely freeze.
It stops accepting any input, and does not ever refresh.
Some times if I run 'beep' command over SSH, it wakes the serial console up.
Or if I connect my Dell D3100, it also wakes the serial console back up.
I do not understand why this works. It was the latter that allowed me to inch through setup to get Debian installed.
I am at a loss as to why this happens.
I have had it happen as early as the moment the kernel is loaded, or as late as 10 minutes after logging into the shell, with the serial console.
The serial console is at 115200 baud. This device has a AMD Ryzen Embedded V1500B CPU.
This system does not have any HDMI/VGA/DVI/DP Output. I only have this UART interface.
If anyone has any insight, or needs any additional info, please let me know. Thanks!
