The CD refused to boot into full graphical/install mode so I used text install. It looks like the system now freezes when there are certain graphical applications being run. glxgears always makes the system freeze. I'm sure there are others, but this one is easiest to test. Interesting tidbits: * glxgears runs smoothly for a second or two before the freeze. * there's a bit of very faint high-pitched whining (apparently from my video card) while glxgears is running. Not sure if that's normal. Never had problems with this card before, though. * SysRq/REISUB doesn't work. I've tested it without the freeze and it works like a charm, then. </blockquote></div> Except for the whining I'm also experiencing hard lockups with Fedora 10 i386 when running something as simple as glxgears for a few seconds. (system is an Athlon64, nForce4 chipset, Asus X800XT videocard). My guess is the videodriver; there are some bugs filed against the R300/R400 cards in bugzilla, but noone seems to be working on it...
