I was not able to find the root of the problem. However, I have many message telling me the following:
Radon 0000:01:00.0: no ffff880214144000 via 0x024000000 conflicts with (no ffff880213ffcc00 0x02340000 0x03340000)

And at some point:
gnome-shell segfault at 14 ip 00007f20b053a82a Sep 00007fff23165000 error 4 in r600_drive.so[7f20b0418000+405000]

I'll continue investigating the bug, but each time I go back with kernel 3.2 (no virtual address space), it works like a charm.
