- FreeBSD 3.3 release
- an atapi cdrom with audio support (unknown brand)
- the port audio/dagrab installed

	

>Description:

When grabbing a specific track from a specific audio cd, the kernel
panicks:

Fatal trap 12: page fault while in kernel mode

fault virtual address            = 0x181b4
fault code                       = supervisor read, page no present

trap number                      = 12
panic: page fault


This is completely repeatable, using this audio record...
>How-To-Repeat:
This is completely repeatable, using this audio record...

just 'dagrab 2' kills the computer after about 10 seconds

 The ATA and ATAPI drivers were completely rewritten between 3.x and
 4.x.  Does this problem still occur on recent versions?
