           Summary: x86_64 with Radeon 9200 has corrupted image when depth >
                    8
           Product: xorg
           Version: 6.7.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: freedesktopbugzilla at don-lindsay-archive.org


I installed Fedora Core 2 (for x86_64) on a box with an ATI Radeon 9200 (128MB).

Generic VGA operation is fine, so the install went normally, but when I booted
the resulting system, the screen showed only a color herringbone pattern.
Modifying the /etc/X11/xorg.conf (via booting a rescue disk) eventually proved
that Depth 8 worked (even at 1600x1200), whereas higher Depth's all had major
image issues (herringbone, or 2x2 or 4x4 duplication), even at 640x480.

I would guess there's some code in the Radeon driver which isn't 64 bit clean.

Box: AMD64 3000+ on "ASUS K8V SE Deluxe" motherboard.
Monitor: Decaview V400 ("DCVe400"), which the install treated as Unknown. Xorg
seems to deduce a Modeline as good as my old hand-done one, thank you guys.
