Radeon KMS doesn't work.

Radeon KMS doesn't work.

[Wakko Warner]

I have a Dell Inspiron 5100 with an ATI Radeon Mobility M7 (7500 R100
PCI ID 1002:4c57 sub 1028:0149).

Immediately when radeon.ko is loaded, the screen goes blank (The backlight
stays on).  I have fbcon compiled into the kernel (I also tried as module). 
I am unable to get the screen to work again until I reboot.  The logs did
not appear to have any errors after the module loaded.  The system was still
responsive on the network.

I tried kernels 2.6.33 and 2.6.34.

I can provide kernel output if needed.

I need to add that if I use modeset=0, the screen does not blank.

Also 2.6.34 (with modeset=0) doesn't do 3D very well on this system.  Some
objects look ok, some are garbled, some do not appear at all.  The gears
from xscreensaver does not show up at all.

Hi Wakko,

as nobody seems to have answered yet, I think it's better that you file a bug 
against the radeon driver (bugs.freedesktop.org, one bug for each defect). 
There may be similar bugs already, so please check this also.

Thanks

I've hit a couple of things with radeon as well.. the first was this:
http://lkml.org/lkml/2010/6/6/172
(if your hitting this issue, then the patch should work and/or it should 
already be in the main tree).

then a few days ago hit another:
https://bugzilla.kernel.org/show_bug.cgi?id=16335
(keep in mind still uncertain on a fix for this, reverting the commit 
gets me up and running(I created a patch, but an umsure if it's a right 
solution)).

if none of these are what your hitting, then maybe(if you can) do a 
bisect on this!

Doesn't appear to be.  I mentioned above that I have no errors.  I forgot
about it saying something about the BIOS.  It shows this
[drm:radeon_get_bios] *ERROR* Unable to locate a BIOS ROM

This one appears to be X related.  In my case, this happens immediately at
radeon.ko load (with modeset=1).
Verification of this was booting with init=/bin/sh and modprobe radeon. 
Instant black screen.  The backlight stays on.

I tried 2.6.32.15.  I noticed that KMS was in staging.  This one didn't do a
black screen.  I saw mostly white, green and a pinkish color.  All were kind
of washed out and were in vertical lines.  KMS on this laptop has not worked
with stock kernels.

I booted Ubuntu 10.04 live CD and it appears that KMS was working.  I don't
know what patches they have in the kernel for this or what is different.

I think this is the same cases with (http://lkml.org/lkml/2010/7/5/44)
And the fix for this bug is in -tip tree, commit 2463eb8

Could you please try following patch?

applied.. o.k. system started without hitting the crash I was 
experiencing!! Thanks for this.. I'll run this and let you know if I 
experience anything out of the ordinary..
