Console boot output showing repeated bnxt_intr STUB messages

I am encountering a critical issue when running OPNsense (FreeBSD-based) on an
HPE ProLiant DL20 Gen11 system equipped with an HPE 10Gb SFP+ PCIe x8 network
adapter (P26259-B21).

During system boot, the kernel repeatedly logs bnxt_intr STUB messages. As a
result, OPNsense fails to complete the boot process and does not reach a usable
state. The issue appears to be related to interrupt handling in the bnxt(4)
driver.

This makes it impossible to operate OPNsense on this hardware configuration.
Hardware:
-Server: HPE ProLiant DL20 Gen11
-CPU: Intel Xeon E-2436
-NIC (problematic):
 -HPE Ethernet 10Gb 2-port SFP+ Adapter
 -Spare Part Number: P26259-B21
 -PCI-Express x8
 -Broadcom NetXtreme-E based (bnxt driver)

Error Messages/Symptoms
During boot, the following messages are printed repeatedly and indefinitely:
bnxt0: STUB: bnxt_intr @ /usr/src/sys/dev/bnxt/bnxt_en/bnxt_txrx.c:716

Additionally, the following message appears:
uhub_explore: illegal enable change, port 1

Due to the continuous interrupt-related messages, the boot process stalls and
OPNsense never finishes booting.
The system does not reach the login prompt or web interface.

A photo of the console output during boot is attached.
