Thanks Sephe, I think you're on to something.  I have some
debug code in the driver to simulate mbuf allocation
failures and when I enable that I start receiving the same
error messages Tom reported (along with various kernel
panics), but when I include your change the system seems
to keep humming along. =20

I'll certainly add your code into an update shortly.

Dave
