Sound still works but interrupts aren't generated. I tried bisecting but I haven't gotten good info yet because it seems that this is not completely reproducible -- sometimes when I load the module, it works fine, and other times I get the message. I think this is a regression, since I don't recall ever seeing the message with 2.6.22 or so. Any idea on how to help debug this? Thanks, Roland
