I tried to set different latecies in BIOS, and for the BTTV module (latency parm). It did not help.
Under Windows the audio driver and the video driver of the card is using different interrupts. (audio 11, video 18) But under linux it uses the same irq (11). Under windows ACPI is enabled.
How can I enable it under Linux? I have ACPI module in kernel 2.4.21 compiled. But it doesnt affects IRQs, when I load it.
How can I use it? Will it help?
What other latencies should I try to modifiy to prevent bttv from freeze? Some hints, please!
