           Summary: System hangs when starting X using Radeon and modes.
           Product: xorg
           Version: 6.7.0
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Driver/Radeon
        AssignedTo: xorg-bugzilla-noise at freedesktop.org
        ReportedBy: sbrenneis at surry.net


I am attempting to use Xorg 6.7.0 on my Linux 2.4.26 system. The system is
running on a dual 800 MHz Pentium-III Intel motherboard with 1GB of memory. The
video card is an ATI Radeon 64MB DDR (Radeon 7200). My kernel has MTRR support,
ATI agpgart support, and DRI support for the Radeon built in.

Xorg -configure generated the xorg.conf file attached. This file works fine as
is and startx starts a 640 x 480 desktop (I'm using fluxbox window manager). I
can add a "DefaultDepth 24" to the screen section and all is still well.
However, if I add a Modes line to the 24depth section that has anything other
than "640x480" in it, the system hangs. The system and kernel logs do not
indicate a kernel panic (or anything else, for that matter). The system appears
to simply stop. I have tried changing the video driver to "radeon" with the same
result and I have also tried using the 16-bit color depth, same result. This
happens when running X directly or from startx.

This appears to be similar to Bug #1384, but the hang occurs at a different
location. Logs will be attached.
