I would rather find the real problem. Also, I don't know how easy it would be to adapt debian unstable. However I self compile the kernel. It had CONFIG_PREEMPT and CONFIG_PREEMPT_BKL. After disabling CONFIG_PREEMPT, I can get rid of that patch and everything works fine, wait_event_interruptible_timeout no more gets interrupted. Also, the problems with replaying Dolby Surround went away, for full log messages see my first post: StartHWFilter error buf 0b07 0010 012c b96a ret fffffe00 handle c041 Is it a known fact that these drivers might not work in a preempting kernel which I simply did not know about? If so, maybe the drivers should put warnings into syslog? I can do more tests if you want me to. As a starter, I could try to enable only CONFIG_PREEMPT but not CONFIG_PREEMPT_BKL -- Wolfgang
