Hi,

I've tried ATI Catalyst 7.12 and 8.1 drivers both with the ATI installer and with the livna packages on Fedora 8 (x86_64, fully updated). My system, with the Sapphire HD 2900 Pro (100212SR), either freezes with a black screen or restarts. I have the system connected to my plasma TV (Pioneer PDP-5070PU). I recorded appropriate timings for the TV using PowerStrip 3.76 in Windows.

Almost all my xorg.conf variations lead to the following at the end of Xorg.0.log:

[atiddx] ASYNCIO init succeed!
Receive enable interrupt ret message
...irqEnableMask: 20008000
...dwIRQEnableId: 00000006
Receive enable interrupt ret message
...irqEnableMask: 10000000
...dwIRQEnableId: 00000008

...dwIRQEnableId: 00000009
Receive enable interrupt ret message
...irqEnableMask: 20000400
...dwIRQEnableId: 0000000a
I've tried things mentioned here:

...and here:

...including the downgrade of xorg-x11-server to FC7. Nothing seems to work.

Here's my xorg.conf:

As you can see, I've commented out options to try cloning the display onto the TV's PC input. But I'd be glad to get anything working at this point.

Thanks for any assistance you can lend!
