Comments/Problems:

Passing a preseed.cfg file, the installation becomes stuck with the following message:

```logs
Detecting hardware to find installation media  ... 2%... 95%... 100%
Detect and mount installation media
-----------------------------------
Your installation media couldn't be mounted. When installing from CD-ROM, this
probably means that the disk was not in the drive. If so you can insert it and
try again.
Retry mounting installation media?
  1: Yes [*]  2: No
Prompt: '?' for help, default=1>
```

In this state, the ISO is booted via USB, so it's a bit strange to get this message.

This is running in a CI environment where the testing is done remotely on the device. If there is a way to get the installer logs from a serial console, please let me know. I have attached the preseed.cfg file and Debian kernel logs.

The same installation method is working on different HW.

Thanks,
