Serial console not interactive anymore after upgrade to 25.1

[kingfisher77]

After an update to 25.1, the serial console is no longer interactive, i.e. I see the output during the boot process, but I cannot log in. There is no prompt, the output stops at 'lo=: link state changed to UP'. It seems that there is a bug in version 25.1. Another person in the german forum reported a simillar issue.

The interactive serial console worked for years up to version 25.1. Now no interaction is possible.

My console settings are as follows:

Console

Console driver
- [y] Use the virtual terminal driver (vt)

Primary Console
- Serial Console

Secondary Console
- VGA Console

Serial Speed
- 115200

USB-based serial
- [n] Use USB-based serial ports

Console menu
- [n] Password protect the console menu

Hi there,

yesterday I made the same experience.
I tried to update my PC Engines APU.1D4 Board running for years with OPNSense to 25.1

Update via Web Interface didn't finish after 2 hours.

I tried a new install with the 25.1 nano edition.
The system booted, but the serial interface stopped sending at a specific point. I wasn't able to do anything from the serial interface.
Same with the serial edition.

After hours of trying I switched back to 24.7 using the serial edition to directly import my backuped configuration.
This worked.

I won't touch the 25.1 until there is a fix.

My upgrade to 25.1 (from a 24.7 serial console) worked well on a 2013 Deciso AMD machine. For me it's just the effect with the serial interface in 25.1 that you described.
