           Summary: radeonfb, switching from X to console locks up system.
    Kernel Version: 2.6.8-rc1
            Status: NEW
          Severity: high
             Owner: jsimmons@infradead.org
         Submitter: jose.l.cordova@seagate.com


Distribution: FC2
Hardware Environment: Intel D865GLX, 3.2 GHz hyperthreaded P4, ATI Radeon 9600SE
Software Environment: fb consoles, gnome

Problem Description:
I have upgraded to 2.6.7 with patch-2.6.8-rc1.bz2 (earlier versions seem to have
other radeonfb problems). After fixing the kernel oops reported in
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=125841
using patch
https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=101570&action=view,
I could  install the new kernel with built-in radeonfb support. But now, the
system crashes when exiting from an X-session.

Steps to reproduce:
The system boots up and looks perfect, with two cute penguins and all. The
following happens regardless of whether I start at init 3 and run startx from a
console or go directly into init5. My Gnome session starts flawlessly, and if I
cat /proc/fb I get the 9600 information. The problem is when I either log out
from gnome, or try to access a console via ctrl-alt-f#. The consoles are pure
garbage, and the system is hard-locked, requiring the reset button.

For the x drivers I am running with module support for agp, agp_intel, and dri,
but I am using the proprietary ATI driver fglrx to get 3D acceleration (this, by
the way, also works well using both the kernel of the internal agp support).

I don't know how to get logs for this, since the system dies completely.
