Mmmhh... It doesn't look like it. The irq19 rate remains constant, and
top doesn't show more than 3% cpu on intr.

xl0: <3Com 3c905C-TX Fast Etherlink XL> port 0x3080-0x30ff mem 0xd0101800-0xd010187f irq 19 at device 8.0 on pci2
xl0: Ethernet address: 00:e0:81:27:cb:3b
miibus0: <MII bus> on xl0

514,p2,0$ vmstat -i | grep xl0
irq19: xl0 ohci0                  787787         13

Any other thoughts?
