Just FYI, I also get this behaviour with my SB 64 AWE ISA PnP card and a recent -CURRENT. The 'hwptr went backwards' messages are triggered most often by heavy disk access (esp CVS operations), compiles and using the Linux emulation, but sometimes by using the mouse on the console as well (this is a serial mouse) Of course, bloated software makes things worse, so RealPlayer is a really bad offender. The messages did not start with SMPNG but got a *lot* more frequent in the last couple of weeks, making listening to mp3-s a real annoyance during any more serious system activity. (Earlier, ie in the early fall and in the summer) these messages were almost never seen while in console mode, but only with X and RealPlayer messing things up. The sound card works fine otherwise. (have not tried recording.)
