I'm under Linux currently - sorry. If it's absolutely needed - just let me know.
When I'm playing some sound file, and very soon I want to play a new one, "play" utility becomes "frozen" for about 2-3 minutes - then ends it's action without any sound output. The same when using other playing utilities, like "splay" or "mp3blaster" (or just any other program, which is trying to make any sound, and because of this is accessing the sound device) - so, it seems for a little bug still remaining somewhere inside.

Very easy - just making the try the way described above.

 I am sorry I took so long to respond, real life kept me busy a while.  I 
 downloaded a snapshot from the following URL and made a bootable install CD.

 The INSTALL kernel booted and ran just fine, but the GENERIC kernel 
 would crash.  After I removed the GUS PnP card, GENERIC booted fine.  I 
 have included captured kernel messages at the end of this email.

 The GUS PnP ISA card belongs to a friend, but he is unlikely to need it. 
   If anyone wants to indefinitely borrow the card for NetBSD 
 development, they may.  The only condition is that on request the card 
 be returned to my friend.



 Here is an excerpt hand-written from the console messages before the 
 crash.  It is interesting to me that it mentions 4 memory banks, but I 
 only saw 2 dimm slots on the card.

 Here is the dmesg from the system with the GUS PnP card removed.
