>Description:
SMP kernel panics with pretty much the same thing. Under 3.5 this particular problem did not rear its ungly head.
I am running a dual pentium 200 with 96megs of RAM on a Tyan Tomcat motherboard. Two 4 gig ide HD, Riva TNT 3d graphics blaster, sound blaster 16 sound card. Oddly enough, when I play MP3 on the dual processing kernal it use to just hang. I would then have to reset the system. But now, it seems sound plays just fine, well the few times I've tried it.
Here is some debug information. If you would like more information let me know and I would be more than happy to get it. Just be sure to tell me how the information is to be gotten and I'll get it.

>How-To-Repeat:
Boot my system and wait. Seriously. Hard telling when the kernel will panic. This particular time it was in making a ports package. Under a single CPU kernal the problem does not occur.
