Problem Description:
I have a board and a video card that support hybrid crossfire. If I turn on the onboard graphic feature the init dies with kernel panic.
The problem was also reported on other places on the Internet.

The interesting thing is that AMD's current closed source (linux) graphic driver support hybrid crossfire.

Steps to reproduce:
Turn on the Surround View feature in the bios (turning on the onboard graphic).
Boot a kernel (I've tried i386 and amd64)
The init dies with kernel panic.
(windows works fine)

geeze, there isn't much to go on here.  I can't find a complete trace of
the kernel crash anywhere.

I've made few picture.

the first two made with quiet boot parameter, and the last two made without it.
Comment 3 Thomas Gleixner 2009-01-14 02:16:23 UTC 
That does not help much. Is there a chance that you can log the boot messages including the panic with a serial console ?

Add "console=ttyS0,115200" to the kernel command line and connect the serial port to another PCs serial port. On that PC run a terminal program (e.g. minicom) and capture the messages which come along.

Thanks,

Can you please provide one with the crossfire thingy disabled for
reference ?

my current dmesg

this is from /var/log/dmesg. I hope it'll be enough.
Is there any kernel (debug) option I can recompile my kernel with to help debugging the problem?

Can you please redo the capture of the crossfire enabled boot (w/o
quiet) and add "ignore_loglevel" to the kernel command line ?

Thanks,

ignore_loglevel

I hope it'll help
Comment 10 Thomas Gleixner 2009-01-14 16:34:57 UTC 
Please add "initcall_debug" to the crossfire enabled boot as well.

Thanks,

I've found a kernel that works with onboard video enabled. My motherboad has an embedded linux (ExpressGate 1.3.3.1 (SplashTop)) and it boots up flawlessly with the onboard graphics enabled. I don't know what kernel it use, but it's source (config) should be available somewhere.
Comment 12 Balázs Hámorszky 2009-01-14 18:58:46 UTC 
according to http://www.splashtop.com/open_source.php the kernel express gate use is 2.6.20

This bug should be closed (marked as duplicate).

FYI, bug #11714 was marked duplicate of bug #11541 which in turn is
solved with a patch that is on it's way to mainline kernel.
