That sounds like the card isn't able to transfer receive data via the
PCI bus fast enough.

wm0 at pci0 dev 2 function 0: Intel i82540EM 1000BASE-T Ethernet, rev. 2
wm0: interrupting at ioapic1 pin 1 (irq 10)
wm0: 32-bit 33MHz PCI bus
wm0: 64 word (6 address bits) MicroWire EEPROM
wm0: Ethernet address 00:c0:9f:22:a9:51

Why is the machine not running in 66MHz mode although you've got a
server motherboard? Try to put in a slot which supports this.

In my experience the Intel cards are the best cards out there. They are
fast and very reliable. In your case it looks like you should find a
faster slot for the card. If you only have 64Bit 33MHz slot available
you should buy a 64Bit Intel card.

	Kind regards
