           Summary: Kernel DRM/Radeon KMS BSOD on HD6850-NI
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: spamjunkeater@gmail.com


Using 2.6.38-rc1 vanilla,
When I try to load radeon kernel module with

modprobe radeon modeset=1

I got BSOD, computer doesn't give any response to me. CTRL+ALT+DEL don't
working nor my main computer switch. 

modprobe radeon modeset=0

doesn't make such problem and computer looks working. But my Northern Islands
(HD6850) card doesn't support Gallium3D without KMS.

Thanks.

Have you installed the necessary ucode for your card?
http://people.freedesktop.org/~agd5f/radeon_ucode/
BARTS_mc.bin
BARTS_me.bin
BARTS_pfp.bin
BTC_rlc.bin

definitely, right to /lib/modules/radeon directory.

If you are using an initrd make sure the ucode is built into the initrd.

I don't create initrd by hand. Used make install to install code and initrd
doesn't have any radeon modules.So initrd doesn't have ucode. But I thought
that is just for boot with radeon module loading. I don't use that feature. 

AFAIK Since I do not load radeon module on bootup, It's doesn't necessary to
have those files in initrd and load from /lib/firmware/radeon/ directly.

Does it requirement that having ucodes in initrd for running NI class cards? My
internal 790GX GPU could woth with KMS without any ucode and modules in initrd.
(At least with 2.6.37, I don't test it with 2.6.38-rc1 and 790GX disabled from
bios since HD6850 plugged in).

Now tested my old 790GX and it's working with my setup but NI.

Removed
BARTS_mc.bin
BARTS_me.bin
BARTS_pfp.bin
BTC_rlc.bin
files from /lib/firmware/radeon. I expect that will make radeon.ko cannot found
required ucodes and will not activate KMS and loaded as modeset=0. AFAIK That
happens when I don't put required ucodes to fw directort with my 790GX when
initial r600 support comes... 

So, when I try to load radeon without those ucodes on firmware directoy, result
is same. BSOD. That make me thinking if it's not related with ucodes...
Thanks

The ucode is required for all asics when the radeon drm is loaded.  Most likley
your initrd already has the ucode for older asics.

radeon module loaded and work as intended.
I use
"modprobe radeon pcie_gen2=1"
and it works
Weird thing is that I enabled GEN1 on my MB bios.
Mesa gives segmentation fault but could use KMS properly now.

Sorry for disturbing.
Thanks.

Created an attachment (id=42226)
 --> (https://bugs.freedesktop.org/attachment.cgi?id=42226)
dmesg of HD3300+HD6850

Previous comment is wrong. Bug is not solved but I just enabled 790GX from bios
with surround view....

So bug is not solved with that flag. "modprobe radeon" working now because of
790GX internal GPU.

I attach the kernel messages. Might be useful to understand problem. KMS looks
loaded...

Yes it fixed the problem. :)
Now loads KMS thanks.

Also I noticed a failure on module load.

...
[drm] ib test succeeded in 0 usecs
failed to evaluate ATIF got AE_BAD_PARAMETER
[drm] Radeon Display Connectors
[drm] Connector 0:
...

I wish its not important.
Thanks
