Comment 2 for bug 193690

Did some more testing: as the frame buffer text mode is distorted on these machines, it may be a bad idea to try using the fbdev driver for X. But it may give a hint. I tried it: well, the whole system hangs. To be more precise: X just dies, leaving the attached log. The screen remains black. And trying to start another (via ssh) results in a hang, where the machine still answers to ping but ssh login stops working. Restaring the machine leads into this state, as the system tries to restart X a few times. This is probably a symptom of this same bug, which makes me think that it is not in the ati driver, but somewhere in the core.
