Watchguard 750e boot issue with 19.1

[errorcode67]

First off new to OPNSense and running the most basic config possible.
Watchguard 750e (8nics) i386 serial.

I have been able to install 18.7 without issues but when I upgraded to 19.1 I cannot boot. Stops at error loading kernel. I have tried a fresh load of 19.1 and still get the issue.  Fresh load of 18.7 boot fine again until I update.

Thoughts?
