Check your dmesg output, and I bet you'll see that bge0 is sharing an
IRQ with another device. (If not, I'd like to hear about it.) This
bug was fixed in -current in revision 1.41 of if_bge.c, but it never
got merged to -stable. I have a patch for -stable that I am planning
to commit after the source freeze lifts. It is attached to this mail.
Please let me know whether it solves your problem or not.
John
