The hdaudio driver is supposed to be unchanged since the previous 
version. Apparently there is a bug that was introduced before this drop. 
Do you know what was the OSS version you were running before this one?

You may compile the snoopy utility (located in the utils subdirectory) 
and send the output to me (hannu at opensound.com).

cd utils
make snoopy
./snoopy > some_file.txt         (This needs to be done as root).
