Total system freeze on ATI 3D driver enable
MSI Platinum P35 mobo with 2.6Ghz Dual-Core, 4GB of PC2-6400 RAM and a Sapphire 2600HD Pro ATI PCI-E video card.
Installing Fedora8 (or Ubuntu 7.10 which I also tried to make sure it wasn't just a Fedora thing) works fine. The generic VESA drivers are installed and the display looks good at 1280x1024, albeit non-accelerated.
Downloading the driver from ati.com and installing it results in an utter system freeze the instant it's activated. Can't even ping the NIC from another machine, it's dead.
In Fedora I tried both installing the driver from ATI and manually installing as well as enabling the Livna/RPMFusion repo and allowing it to. For Ubuntu I also tried both the stock driver from their site as well as enabling the Ubuntu-provided version. Allowing Ubuntu to take care of everything related to enabling it at least didn't totally lock the machine, it tried enabling it and when that failed came up with a generic driver. Booting Fedora with it enabled definitely kills it though, no ALT-F1 or any other type of input.
Ideas? Hardware-wise everything is pretty much stock, BIOS "fail-safe" settings, etc...
