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.
