afte the screen goes blank or not at all ? Can you send the
full dmesg log too ? Also, enable radeonfb verbose debug in
Yes, there were more in /var/log/syslog:

Do the "seems to be busy." and/or "Failed to register I2C bus"
indicate a problem ?
There's nothing about radeonfb in dmesg because I manually
loaded the modules.
I now compiled built-in with debug enabled and got the same
problem. Nothing got logged. Everything seems to stop when it
blanks, but SysRq works.
