A workaround in to disable KMS at boot: I added radeon.modeset=0 in the kernel 
options of the grub configuration and the problem seemed to disappear. 
Here is the related line in /boot/grub/grub.cfg:
 linux   /boot/vmlinuz-2.6.32-21-generic 
root=UUID=2aa5a050-dd81-4fca-83ba-c269a8dbdc96 ro   quiet splash 
radeon.modeset=0
