I have made a custom debian iso for old hardware (including both 32 Bit and 64-bit versions). Due to the latest Debian release I decided to port it to Debian 12 Bookworm rather than Bullseye. I have been using live_build for compiling the iso, it worked perfectly for bullseye but for debian 12 it causes kernel panic if i assign ram less than 1gb. The distro on its own does not take more than 200mb of ram, I even tried making a netinst iso using live_build but still the same issue. After installation(using more than 1gb of ram) i can reduce ram allocation upto 512mb with no issues but the installer doesn't work with less than 1gb of ram.
The following are my lb config settings:
lb config -d bookworm --debian-installer live --debian-installer-distribution bookworm --debian-installer-gui false --archive-areas "main contrib non-free non-free-firmware" --debootstrap-options "--variant=minbase"
Please guide me if I am doing something wrong.
