Description Luigi Italiano 2010-02-28 22:00:02 UTC

When try to boot from the DVD, the system stop just after the BTX load and reboot.

This happens to motherboard with AMD/ATI SB700 or SB750 chipset, just when the onboard RAID controller is enabled. IDE and AHCI mode are ok.
The same problem appears with DragonFlyBSD 2.4.1.
FreeBSD/i386, NetBSD and OpenBSD have no problem, as Linux and Windows.

Motherboard tested:
Asus M3A78 Pro; chipset AMD 780GX / ATI SB700
Asus M3A78-T; chipset AMD 790GX / ATI SB750

How-To-Repeat: Just try to boot the cd/dvd

Can you provide more details about what is on the screen when it dies?  Do you 
get far enough to get to a loader prompt?  Can you possibly get a screen 
capture before it resets?

Update: same problem with FreeBSD/i386, I have tested the last snapshot 
and it can't boot.
As stated before, it is impossible to get screebshots or any kind of 
information, the system reboot almost immediately after the rolling 
cursor of BTX appearing on screen.

The raid on this motherboard is a fake. So, we just need to disable raid
and use gmirror for freebsd.

Of course, if we need RAID 1, but it is just a workaround, not a 
solution. Even if FreeBSD does not support this kind of fakeraid, it 
should not automatically reboot.
Traditionally, FreeBSD works very well with this kind of hybrid RAID 
controllers, one of its point of strenght, so I think this issue must be 
investigated.

Please use digital camera to obtain screenshots (you can then post links to them).
Or even better use serial console to do proper debugging.
Without technical information we won't be able to help.
