Description girgen 1999-10-28 02:40:00 UTC

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
instructor pointer               = 0x8:0xc0134f50
stack pointer                    = 0x10:0xc659bccc
frame pointer                    = 0x10:0x659bcf0
code segment                     = base rx0, limit 0xfffff, typ 0x16

processor eflags                 = interrupt enabled, resume, IOPL=0
current process                  = 758 (dagrab)
interrupt mask                   = net tty bio cam
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?
