           Summary: Radeon + DRI on r300: X goes 99.9% CPU
           Product: DRI
           Version: XOrg CVS
          Platform: All
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: high
         Component: General
        AssignedTo: dri-devel@lists.sourceforge.net
        ReportedBy: [EMAIL PROTECTED]


Hi,
I've just installed the latest versions of X on my machine,
and enabled DRI (I waited more than 2 years for it to work...).

Overview:
Everything works OK, until I switch to console.
When I try to come back to X (Fn+F7) X goes 99.9% CPU and keyboard
is disabled (mouse works). The only way out is hardware power-off
or ssh from another machine and reboot. 

I saw similar bugs, but either for different drivers (nVidia) or
other which were not the same.

Steps to Reproduce: 
1. Enable DRI (set NoAccel to false).
2. startx
3. Move to console (Ctrl+Alt+F1).
4. Move to X (Ctrl+Alt+F7).

Actual Results:
X goes 99% CPU, keyboard is disabled (mouse works).
Network and other (mpd- music) is working, so SSH can be done.
No specific issues in the log file.

Work-around:
1. Use NoAccel (disable DRI).
