[Bug 41732] New: [radeon] KMS (and X.org) detect wrong outputs

           Summary: [radeon] KMS (and X.org) detect wrong outputs
           Product: Drivers
           Version: 2.5
    Kernel Version: 3.1-rc3
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Video(DRI - non Intel)
        AssignedTo: drivers_video-dri@kernel-bugs.osdl.org
        ReportedBy: niels_ole@salscheider-online.de
        Regression: No


On my notebook, 6520G (mobile A6 APU), KMS detects a screen on VGA-0 although
there is no attached. Because of that it chooses a lower resolution than the
internal display's native resolution. The selected mode causes the internal
display to flicker, though.

In dmesg, I can see the following:

[drm:atom_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting
[drm:atom_execute_table_locked] *ERROR* atombios stuck executing E3E6 (len
2585, WS 4, PS 4) @ 0xEAD0

Other issues I have with this :
- xrandr reports a size of 0x0 inches for the internal display
- the internal display uses only 6 bit/pixel and there seems to be no way to
enable dithering
- the brightness controls do not work although there is a sysfs acpi interface
that gets updated
- the display does not come back on after standby

These issues may be unrelated and I will create further bug reports if so, but
maybe they give a hint concerning this issue.

When I run rmmod radeon and insmod radeon after standby via ssh the screen
stays black, too.

It seems that the radeon module cannot find any edid information at all.

Is there anything I can do to debug this further?

dmesg output with drm.debug=4

note: radeon_fp_native_mode gets calld for LVDS although get-edid can find
valid edid data for it (see next attachment)

Please attach a copy of your vbios:

(as root)
(use lspci to get the bus id)
cd /sys/bus/pci/devices/<pci bus id>
echo 1 > rom
cat rom > /tmp/vbios.rom
echo 0 > rom
