Sorry for disturbing the silence, but radeon seems to have issues. I
tested -rc3 (and after that -rc1 which also has the issue) on my Laptop
and it just reboots after (or while?) GFX initialization. The last lines
of dmesg are:
Freeing unused kernel memory: 624k freed
Write protecting the kernel read-only data: 8192k
Freeing unused kernel memory: 1456k freed
