This suspiciously looks like bug report 235246. See:

The issue seems to be resolved in 12-STABLE. In your case maybe you 
could work around the issue by disabling msix, as suggested in the 
comments to the bug report. I.e. put


in /boot/loader.conf and reboot the system.

Hope this helps.

Kind regards,
