FreeBSD elfman.deadheaven.com 4.0-STABLE FreeBSD 4.0-STABLE #0: Sun May 28 12:49:35 PDT 2000     davidski@elfman.deadheaven.com:/usr/src/sys/compile/EFLMAN  i386

>Description:
The commits cg MFCed to pci/sound in May included new support for SB Live-type sound cards.  Compilling this support on Dell Dimension XPS T systems equipped with this card does detect the sound card properly and allow the appropriate devices to be created.  Any attempt to playback sound, however, will result in an immediate page fault panic and a system reboot.  This has been confirmed with other Dell Dimension XPS T series users on the -STABLE list, though some report only problems when using ECC RAM.
>How-To-Repeat:
1) System is DELL XPS T 850 w/ECC RAM.
2) Add device pcm to kernel and build.
3) Attempt to cat sound, use mpg123, or xmms will result in instant panic.
>Fix:
Unknown.
