there are a variety of things that can block for between 16 & 300 ms (not necessarily IRQs). what size fragments are you using?2K. I have to rise it to 8KB to work fine. My friend with the G4 still have very few interruptions even with 8KB.
OK.... if you can't do with such large fragments .... You might want to try Andrew Morton's Low-Latency patch (URL: http://www.uow.edu.au/~andrewm/linux/schedlat.html#downloads ) it makes things quite a lot better - but we still have a way to go on PPC before we can achieve sub-ms block-free operation. Another thing on the audio TODO list ;-) let me/us know how you do if you try it (last time I did, the patches applied cleanly to the PPC BK tree) - you (could at the time) ignore the x86-specific mods to head.S.
