Subject:   loader crash / BTX halted on 9.0-RC2 DVD with AMD pseudo-RAID
Message-ID:  <848DEEC1-570F-43F8-B432-A34F81014CD0@jnielsen.net>

This weekend I downloaded the Freebsd 9.0 RC2 amd64 ISO image and burned =
it to a DVD. I have a computer that currently runs Windows 7 but I plan =
to install FreeBSD on it in the near future so I booted it up from the =
DVD to check the hardware/driver status. Much to my dismay, the boot =
loader crashed right away (register dump followed by "BTX halted") and =
the computer immediately rebooted. I took a video with my phone so I =
could capture the crash message, screenshot here:

http://picpaste.com/pics/BTXcrash.1321899682.jpg

I then tried tweaking a few BIOS settings and found that turning off the =
built-in pseudo-RAID allowed the DVD to boot normally. I changed the =
SATA type from "RAID" to "AHCI". Fortunately I plan to use the =
controller in AHCI mode for the FreeBSD installation so this won't end =
up being a problem for me, but I still thought it was worth reporting.

The system in question has a Foxconn A7GM-S motherboard with AMD 780G =
(NB) and AMD SB700 chipsets. I have a two-disk mirror for the Windows =
installation which is why I had RAID mode enabled in the first place.

In case jhb^H^H^Hsomeone is interested, below is the output from "dmesg" =
and "pciconf -lv" once I booted up in AHCI mode. Let me know if any =
additional information or tests would be helpful. Thanks!

JN
