New install boot failure - black screen v.20.0.0.222

Hi, I'm new to the Sophos Firewall, but not firewall products in general. I've been running pfsense/opnsense for years, and thought I might give it a try. I can get it to boot just fine in a Proxmox VM, but on dedicated hardware it seems to be problematic. It looks pretty great on the VM, but I don't want to expose that hardware, not because I don't trust it, but because I have other services hosted on it that I don't want on an internet facing device.

I'm using a Dell Latitude 7290 i5 (8th gen) with 8GB of member and a dedicated M2 SSD. The install goes off without any issues, but I can't get the OS to boot at all...

I've tried the usual suspects, Disabling secure boot, TPM, messing with UEFI vs legacy boot options, disabling power management, and a host of other BIOS settings. I've also upgraded the BIOS and dropped back to factory defaults. The network card is the integrated one with an external TP-LINK 1Gb USB3 interface that worked great on a pfsense device and my Proxmox cluster.

The boot gets as far as grub, and adjusting boot options to remove the serial console, or just change from quiet to logging=4 yields "Booting a command list". Otherwise, Booting 20.0.0.222 or just a plain old black screen with a solid cursor.

Any suggestions at this point are appreciated.

Best,

Dan

  • Also of note, I have been digging around in the forums, Reddit and just kernel and web forums for a few days now.

    Many of the related posts tend to be either old, related to firmware updates, or that SFOS 18 did not support UEFI, which appears to have changed if I am reading my boot options and success/failure properly. If I missed something that you know about, please feel free to repoint me at other posts.
