Existing users, 
I have a G4 400Mhz AGP with a retail Radeon 8500 card running Panther 10.3.3 and are experiencing random system panics where the computer just locks up and freezes with the beach ball initially an then just the mouse arrow.
The only movement is the mouse cursor which can be moved around the screen but has no effect on anything like the dock or clicking.
The only way to regain control is to turn off the power and restart from scratch.
I'm sure its the driver for the Radeon card as the problem gets more frequent with each system upgrade.
I have also flashed the 8500 with the latest firmware but without effect.
Is anyone else experiencing this problem?

Radeon 8500 Driver Problems - gudrick
I don't have 10.3 and I haven't had any kernel panics, but I can vouch for the 8500's fan being garbage. Mine (also in an AGP 400) failed after 6 months (made weird buzzing noises, and finally it would just stop spinning). I replaced it with the fan from my OEM Rage128Pro and it's been fine ever since.Thursday, April 01 2004 @ 04:12 PM PST
Radeon 8500 Driver Problems - bimble
I can't say what's causing the problem for you, but I have a G4/400 (with a 1GHz upgrade) and a Radeon 8500 running 10.3.3, latest firmware on the card, and the system is quite stable. Definitely sounds like you'll want to look for a hardware problem.Thursday, April 01 2004 @ 05:47 PM PST
Checked your Fan? - pdot
Have you checked the fan for your GPU? I'm not sure if the overheating of video cards can cause problems such as yours, but I know that Ati have a bad reputation for their fans. It's all over the xlr8yourmac forums. My R8500 fan is starting to die out (it speeds up and down, when it's working) and I noticed a slight brown coloring on the fan, which probably happened when the fan doesn't start. A little push with my finger starts it up.Reply to This
