           Summary: Mobility Radeon X1700 (r5xx familly) kernel boot/ module
                    load error (regression)
           Product: DRI
           Version: XOrg 6.7.0
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: pauldv@gentoo.org

Kernel dmesg output (each console switch triggers an invalid framebuffer id
message)

Kernel mode setting does not work for me any more on my laptop. The last
working version is 2.6.32-rc6. 2.6.32-rc8 certainly does not work anymore. I've
also tested with various later versions including 2.6.33-rc7.

When using builtin kms, the kernel just hangs when loading. When using a
module, the loading does not hang the computer, but blacks the laptop screen
(it is completely off, including the backlight). After a while xdm kicks in and
I get display. Switching to a virtual console gets back to the no-display
situation. Also with a second screen attached (on dvi) there is no display.

Do you have fbcon loaded?  You need it for a console on the drm framebuffer
otherwise you will get a blank display until X starts.

I'm not sure about whether fbcon is loaded when built as a module, but it is
enabled in the kernel config. It still doesn't fix the case when built into the
kernel, or the fact that it doesn't activate my DVI output properly (even
running X) even though it sees it (as gdm is nicely asking for
username/password on the dvi screen (presumably))

Can you attach your xorg log and dmesg from 2.6.33-rc7?  Also to clarify:

2.6.32-rc8 and 2.6.33-rc7
- console is blank
- LVDS works when X starts if no DVI monitor is connected
- LVDS and DVI are both blank when X starts if both are connected

2.6.32-rc6
- working console and X on all outputs


Does `modprobe fbcon` enable your console?  Does DVI work if you connect it
after you've started X on the LVDS?

I've tried it this morning again with .33-rc7 (without the DVI screen connected
at all, previously I had the DVI screen connected), and instead of displaying
X, it hung. While it did bring up the network etc, it did not actually give me
ssh access. Also no X.

Also to clarify, the LVDS (and DVI screen when connected) are completely off,
not just blank. As I could not log in, modprobe fbcon was not possible, also I
did not get X.

I've just tried things again, now not relying on module autoloading by udev.
I've explicitly loaded fbcon (which worked, but did not change the screen).
Then I've ran "modprobe radeon" remotely, which resulted in turning of the
screen and first for a long time locking the ssh connection. After a long time
(a couple of minutes) the console prompt appears, and the ssh connection is
usable again. It might be that with the built-in support the same thing would
happen, I just never happened to leave the computer alone that long to notice.

Some further info. While running X on the X server with the .33-rc7 kernel,
when I move the mouse (with KWin compositing mode enabled) I get "horizontal
snow" kind of noise. (btw. Dmesg doesn't say anything)

Indeed the bug seems to be related. Tomorrow I'll try with 33-rc8, as well as
taking a look at reverting some of the commits mentioned in that bug.
