Comment (by waddlesplash):

 Someone reports on FreeBSD that this may be caused by the device being in
 MSI-X interrupt mode but the driver not supporting that:
 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=243992

 Adding support for MSI-X may be easier than trying to disable it. Code in
 question:

 Example of another driver that supports MSIX:
