Have you tried disabling MSI and MSI-X in FreeBSD to see if it makes a
difference?  Set hw.pci.enable_msi="0" and hw.pci.enable_msix="0"
in /boot/loader.conf and reboot.

Nope, :(
Interrupt usage is still around the 89-95% :( 

NB sysctl -a | grep msi   returns nothing, and attempting to set the
values
directly returns 'unknown OID'

this is on 6.2 GENERIC
