           Summary: Unresponsive system on boot with radeon + FireGL v7700
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: noryb009 at gmail.com
          Hardware: x86 (IA32)
            Status: NEW
           Version: 9.2
         Component: Drivers/Gallium/r600
           Product: Mesa

I'm using a FireGL V7700 with Arch Linux x64. When booting to a command line,
when drivers are loaded, the screen goes into power saving mode, and the system
becomes unresponsive.

Booting with `nomodeset' works OK. If I run "$ modprobe radeon modeset=1", the
screen goes power saving mode, the system stops responding to open ssh
session(s), and the caps lock key no longer works (kernel panic?).

I've also tested with a Puppy Linux Live-CD, with the same results
(unresponsive on driver load).

I've tested a HD 4650 in the same system, and everything works fine.

$ lspci -v | grep VGA
