I'm now having exactly the same problem on one of my machines which has
an 3C509-TX card and runs the -current.
It seems the following commit has caused the problem:

Modified files:
sys/pci if_pn.c if_pnreg.h if_xl.c if_xlreg.h
sys/alpha/conf GENERIC
Log:
Make the xl and pn drivers work on FreeBSD/alpha and add them to
sys/alpha/conf/GENERIC.
Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
which means we have to add yet another kludge to make it happy. Since
we can't offset the packet data, we copy the first few bytes of the
received data into a separate mbuf with proper alignment. This puts
the IP header where it needs to be to prevent unaligned accesses.
Also modified the PNIC driver to use a non-interrupt driven TX
strategy. This improves performance somewhat on x86/SMP systems where
interrupt delivery doesn't seem to be as fast with an SMP kernel as
with a UP kernel.
