I admit that I don't know what "no prefetched decode" means in this
context, or what I can or should do about it.
But the same hardware running stable/6 does not issue that whine, and
the laptop in question does see the additional PCI devices on the
docking station when running stable/6, but issues the above whine, and
fails to "see" the additional PCI devices in the docking station running
any of stable/7, stable/8, or head (9.0-CURRENT).
And while there are certainly advances in many respects in going to
newer versions of FreeBSD, I'm a little hard-pressed to understand how
this qualifies. :-}
A bit of background:
My laptop is parts from 3 Dell laptops -- 2 Inspiron 8200s and 1
Latitude C840. I use the FreeBSD bootloader, and have 4 distinct
bootable slices on the disk. At this time:
* slice 1: / and /usr for stable/6
* slice 2: / and /usr for stable/7
* slice 4: / and /usr for stable/8
* slice 4: / and /usr for head (9.0-CURRENT); also swap, as well as a
few other partitions (e.g., /var) that are mounted to the
same place regardless of which slice is booted.
For last night's BAFUG meeting, Julian had volunteered to demonstrate
vimage. He needed access to a machine running stable/8 or head with
multiple NICs.
I volunteered the use of my laptop, as it has a couple of NICs in its
chassis, and I recalled that when I had run stable/6, FreeBSD saw the
wired NIC in the docking station.
So I brought a couple of PCI NICs to stick in the dockinig station,
figuring that would give us 5 NICs (not counting Firewire -- or
anything I could shove in a PCCard slot), which should be adequate.
But as I was building stable/8 (running stable/7 at teh time), I noticed
that "ifconfig" output didn't show the additional 3 NICs.
So this evening, I booted each of the slices in turn to single user
mode, then (in each case) entered:
* fsck -p && mount -a
* csh
* uname -a >/var/tmp/pciconf.N
* pciconf -lv >>!$
* dmesg >/vat/tmp/dmesg.N
(where "N" was one of "6", "7", "8", or "9", according to the version of
FreeBSD being run at the time).
I've attached the resulting files.
Here's the tail end of diff -u pciconf.{6,7}:

I realize this isn't The End Of The World As We Know It -- and
Julian was able to demo vimage with only 2 NICs showing up -- but
I would rather prefer to be able to make use of the docking station
without running FreEBSD 6.x to do so.
[I set Reply-To because I'm (still) not subscribe to -hardware@.]
Clues?
Thanks!
