Installer can't load kernel... after successful installation

Hi,

Not sure if this is the best list for this or not. Thought this was some pretty weird behavior.

I installed 14.1-BETA3 on two Dell Latitude 2120 laptops. Everything works fine as far as I can tell.

I then tried booting the same USB stick with the installer. It hands at load kernel, on both of the laptops.

No BIOS updates or changes since then. Same USB stick works on other machines. Same USB stick with the same image worked to install in the first place.

Using UFS, if it matters. BIOS install (does not support uefi).

Does anyone have any idea of why this might be? I find it perplexing. Maybe a combination of factors, including some BIOS quirk?

At first I thought it must be related to 14.1, but 14.0 installer and mfsbsd also does it.

Thanks!
