So, do you mean loading the driver itself doesn't lock up? If so, it's better than I expected.

Did you run ever PCM playback/capture before that? This is more dangerous :)

Also, please give your hardware details, as there are different models for X-Fi, and some are handled pretty differently.

I think perhaps from uninstalling pulseaudio I got further. I can use mixer now, and it even has a "Master" device, but nothing else...

however, I do get a lock up later.

I get this from running aplay, too, if this helps...

Thanks! That's rather a stupid bug. The patch is below.

Hello, I have tried the driver with the fix you provided, but I couldn't get anything. Kernel panic on any attempt to use sound or mixer. Also kernel panic several seconds after Xorg starts. Each crash causes either hang or reboot so I couldn't get any error messages. If there are some logs left, please tell me where they are and I'll send them to you. My card is X-Fi Platinum Fatality Champion Series.
