Sorry, that wasn't my intention. I was just trying to document my
experience with this particular motherboard (I have a number of others
that work fine with FreeBSD 7-stable, this one I'm typing this on is a
very similar Gigabyte board in fact).

Nope, no keys do anything. You must either push reset or pull the plug.

Well, I can build a kernel if I run the 7.0-release kernel. That's how I
got to 7-stable on the machine in the first place. I used "sneaker net"
to copy it to this one via a CD (as I mentioned, the 7.0 kernel boots
but the Realtek ethernet device is not recognized).

That's what I suspected. The values displayed when doing a "pciconf -lv"
are similar as for this system I'm using to type this, but now that
I look closer and make a direct comparison, the failing device has a
rev=0x02 vs. rev=0x01 for the working one. The pciconf -lv output for
the failing mb is:
[EMAIL PROTECTED]:2:0:0: class=0x020000 card=0xe0001458 chip=0x816810ec
rev=0x02 hdr=0x00
vendor = 'Realtek Semiconductor'
device = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC'
class = network
subclass = ethernet

I'll be happy to try that, but the kernel I most recently tried was from
7-stable
source that I cvsup'd just yesterday. Since both the official 7.1-BETA and
very recent 7-stable hang the same way I suspect that all of the newer kernels
will experience this hang. Let me know if you still think it's worth trying one
of the snapshots. I do plan to try the ATA_STATIC_ID setting that you mentioned
above to see if that helps. Let me know if there is anything else I should try.
I am able to build kernels so long as I run the 7.0 kernel (and work around the
network problem).
Thanks for your time & response!
