Description rem11_1999 2009-11-07 03:42:26 UTC 
Since 2.6.32-rc1 (and up to 2.6.32-rc6) kms failed to start correctly, and in /var/log/message there's :

But firmware is here in /lib64/firmware/radeon/R520_cp.bin.


If I restart a 2.6.31.* without changing anything, no problem :

The driver isn't able to find the firmware.  It was split out of the kernel and into a separate package in 2.6.32.
