Hey there --

I'm attempting to configure an Adaptec 4 port NIC (the 6915 card), and
I seem to have been able to build a kernel that will use it. However,
the machine hangs when configuring the last interface:

sf0 at pci3 dev 4 function 0: ANA-62011 (rev 0) 10/100 Ethernet, rev 3
sf0: interrupting at ivec 10
sf0: Ethernet address 00:00:d1:ec:f5:59
sf0: 64-bit PCI slot detected
sqphy0 at sf0 phy 1: Seeq 80220 10/100 media interface, rev. 1
sqphy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, auto

sf1 starts up....
sf2 starts up....

sf0 at pci3 dev 7 function 0: ANA-62011 (rev 0) 10/100 Ethernet, rev 3
[ hang ]

I'm running NetBSD 1.6. I seem to recall reading about a problem
similar to this while I was researching this card, but I can't find
the reference again (this was probably thread about the quad port
happymeal card, so it was probably not germane anyway). This is
basically a repost of something I asked on current-users a while ago,
so apologies to anyone subjected to my query twice. 

Any suggestions?
