Hi all - I'm sure I'm missing a very simple console setting, but I just did a reload, and now I'm having serial console trouble.

Step 1) Install 25.7 via amd64/vga image
Step 2) Install default dec2752 settings from https://docs.opnsense.org/hardware/defaults.html
Step 3) Patch up to 25.7.10
Step 4) Restore my prior configuration (minus tunables - that is what I'm trying to get "clean" ...)

What is occurring:

Console works fine from BIOS to boot loader to console output.  But once boot finishes and I should be getting the login details, it stops providing output or accepting input right here:

Now if I do something that kicks out a kernel message (i.e. reboot) - I WILL see that output here.

So what setting am I missing?  In System -> Settings -> Administration, the Console settings are as such:

Code Select Expand

Console driver: "Use the virtual terminal driver (vt)" - Yes
Primary Console: Serial Console
Secondary Console: None
Serial Speed: 115200
USB-based serial: "Use USB-based serial ports" - Yes
Console menu: Password protect the console menu

EDIT: Forgot to mention, I did make sure "UART 0 Legacy" is disabled in the BIOS.

Hi all -

Have a brand new, out of the box DEC2752, and I'm having big issues with it.

Basically, configuration goes OK right until I try to use the ax0/ax1 interfaces for anything.  Once I enable those interfaces - I have all kinds of odd issues.   The links come up but never pass traffic.  I've tried multiple SFP+ modules - both fiber and copper - to no avail.

To make it worse, not only do the connections not work, but I also end up with serial console port issues.  The console port stops giving me output.  If I then reboot the box, the boot sequence seems OK right until it outputs the IP assignments ... as it's printing the SSH SHA256 fingerprints, the console comes to a full hang.

This is really, really problematic.

I did a full reinstall of OPNsense - both the business and the community versions - to absolutely no avail.

Any ideas?  Is there something I'm missing about these AMD chipsets?

I'm really stuck right now.
