Ewww, I'm replying to myself in hopes that someone
else has seen something like this:

I'm still having interrupt problems with my sf* card

1) If I do an scp over sf0, no problems at all
2) If I do an scp over sf2 or sf3 (can't try sf1 right now) my
interrupts go nuts, and my transfer rate goes to hell:

However, my interrupts/card look normal:

I've read about some problems on linux with the Quartet64 cards
and the AMI BIOS. I happen to have the AMI bios on this machine
:(

http://www.freelabs.com/~whitis/hardware/quartet.html

But the symptoms they describe don't seem to manifest themselves
on my machine:

sf0 at pci3 dev 4 function 0 "Adaptec AIC-6915" rev 0x03: irq 11 address 00:00:d1:ed:e0:51
sqphy0 at sf0 phy 1: Seeq 80220 10/100 media interface, rev. 1

sqphy1 at sf1 phy 1: Seeq 80220 10/100 media interface, rev. 1
sf2 at pci3 dev 6 function 0 "Adaptec AIC-6915" rev 0x03: irq 11 address 00:00:d1:ed:e0:53
sqphy2 at sf2 phy 1: Seeq 80220 10/100 media interface, rev. 1
sf3 at pci3 dev 7 function 0 "Adaptec AIC-6915" rev 0x03: irq 11 address 00:00:d1:ed:e0:54
sqphy3 at sf3 phy 1: Seeq 80220 10/100 media interface, rev. 1

Bah!
