Our application ships on Dell 7212 PC running the Generic x86_64 image. This image installs fine on this device. The Dell 7212 has been replaced by the 7220 recently so we have to support that going forward. The issue is the Generic x86_64 image does not boot on this device, we tried a few other Intel types but none boots. The image is selectable from the bios prompt but freezes immediately after selected, before even the splash screen is loaded. Booting a Ubuntu 19.04 image on the same machine works fine.
If I can get some trace logs from the tty that would help. What are the debug options I have to try and chase this down ?
