I have had the same problem, as shown here:

According to your pciconf output, your card either doesn't support
MSI-X, or you have MSI-X disabled.
Check the hw.pci.enable_msix sysctl and make sure that it is set to 1.
Also check to make sure there aren't any BIOS settings blocking MSI-X.
Apparently the older Intel gigabit cards don't support MSI-X, and as
such get starved.
I checked and hw.pci.enable_msix=1, so that is on.
Any hints what to look for in the BIOS settings that might block MSI-X??
I'll also be ugrading the bios this weekend to if that will enable MSI-X.
Another solution would be to get a new version Intel Ethernet card?
And stick it in a PIC-X slot?
Or would that again suffer from starvation.
And as a side question:
Why would that starvation actually "crash" the driver/device?
