I'm seeing much the same thing, on an SMP box with onboard sbc0 (Vibra16X) sound chip. Attempting to play sound with madplay gets about 2 seconds of sound and then silence, with the madplay process in an unkillable kernel wait. Oddly enough, the sbc0 interrupt thread continues to occasionally gather a tick of CPU time, but apparently not enough to do anything useful. I'm busy doing binary-search on the CVS tree, checking out source from different times and seeing if I can localize the commit that broke it. My current results are that a kernel built from source as of 2001/08/10 00:00 CDT (i.e. 2001/08/09 22:00:00 PDT) works, one built from source as of 2001/08/10 15:52 PDT does not, so the bug is somewhere in between there. I'm now trying to narrow this down further, to a specific commit somewhere in that region.
