--- Comment #7 from [email protected] --- Radeon driver hangs here. X starts but suffers intermittent segfaulting. The machine never segfaults in terminal (without X running). Early KMS, zero-nada-nil-no power saving or sleep stuff. That's all switched off from BIOS, up through terminal, up to X. Yes, I physically switch off the PC at shutdown. I'm not seeing any flavor of sleep mode. The LCD screen just blanks every now and then; no recovery. Can't get out of X or see terminals. Keyboard is 100% unresponsive. A segfault would explain it. That's what happens now. Under previous settings, I would get a freeze, but the screen would not go blank. It would just hang in place. I tried different AGP and KMS things. I got regular hangs at 8x, so dropped to 4x, which is stable, except videos. Then it's a dice roll. If I set to PCI mode (AGP speed -1) then it's more stable, but videos look garbage. I had to turn off OpenGL in cairo composite manager and use the cairo back end. OpenGL hanged regularly. It's an old machine but ran for many years just fine. I am fairly confident this problem is a video driver and/or settings issue. Here's the data dump.
