Sorry for the delay. This weekend I will do some tests with different buffer settings. Unfortunately, I can only test Activy GR and old-style Nova hardware (budget driver). I'd appreciate if more people would test the patch with different hardware (budget-ci, budget-av, budget-patch driver). Please report _any_ problems. Thanks. Anyway, I still don't like the way buffer warnings are logged. syslog might be flooded with 100 buffer warnings in worst case. I will make error logging rate-limited, i.e. no more than one message every 30 seconds will be logged. The error counter will be cleared after logging the message. That should be sufficient to detect any problems.
