           Summary: [RV740] No KMS with HD4770 and 2.6.33 kernel
           Product: xorg
           Version: 7.5
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: blocker
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org

         QAContact: xorg-team at lists.x.org


I'm currently using the 2.6.33 mainline Ubuntu kernel as it contains the RV740
initialization fix and in UMS it works just fine (have yet to test some games).

As KMS is supposed to be the standard in future distributions, I take the time
to report this bug here to assist in fixing it.

When I try to boot with KMS I only get a screen (although it seems the correct
resolution) displaying various horizontal and vertical bends in all possible
colors like some strange moire effect.

Changing to a VT is not possible too so the system is basically unusable. But
the system itself is still responsive and I can reboot the system with
CTRL+ALT+DEL.

System overview:

- Motherboard: Gigabyte GA-790XTA-UD4
- CPU: AMD Phenom II X4 955 (3.2GHz)
- RAM: 2x 2 GiB DDR3 (1.3 GHz)
- GPU: PowerColor Radeon HD4770 512MB GDDR5
- Monitor: 30" Dell 3007WFP-HC (2560x1600)
- OS: Kubuntu Lucid Alpha 3 + xorg-edgers PPA

I will attach some logs of a KMS boot.
