sfxge driver causes a kernel panic during network startup

Important notices

Before you add a new report, we ask you kindly to acknowledge the following:

• [ x] I have read the contributing guide lines at https://github.com/opnsense/src/blob/master/CONTRIBUTING.md
• [x ] I am convinced that my issue is new after having checked both open and closed issues at https://github.com/opnsense/src/issues?q=is%3Aissue

Describe the bug

For some reason, a SolarFlare SFN7122F 10Gb dual port card does not work on Opnsense 23.1 when installed in an HP 290-p0043w SFF computer (Celeron G4900 CPU) w/ 4Gb RAM. This can be recreated whenever I assign network interfaces from the cli. After confirming my settings the system kernel panics after the network starts. This card works fine on the same computer using Linux (Sophos UTM).

The card also works on Opnsense on a different machine, an HP T620 Plus thin client with an AMD GX-420CA APU SoC w/ 8Gb RAM.

To Reproduce

Steps to reproduce the behavior:

1. From cli, select option 1, assign interfaces
2. confirm choices
3. wait for a kernel panic
4. See error

Expected behavior

No panic.

Describe alternatives you considered

SolarFlare card works fine on another computer with double the ram (4GB vs 8GB). Other than memory the only difference is CPU (Celeron G4900 vs AMD GX-420CA APU SoC)
