Title:
  ATAPI devices malfunctioning

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Won't Fix

Bug description:
  I'm experiencing problems with my ATAPI devices: 
  suddenly they stop working properly and get uncontrollable/disappear, while I 
 got such errors from the kernel:

  > ...
  > [ 1896.913061] ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x2

  I'm not sure if due to this troubles, but I had to remove a DVD-ROM
  device from the system because a audio cdrom literally exploded
  (probably due to too high speed?) and kept getting these errors for
  the other device, a DVD-RW.

  Both devices are Lite-On products and attached on the A8V Deluxe
  motherboards' IDE connectors.

  I'm going to attach additional information to this report: please, let
  me know if you need any other details.

  Thank you in advance for your help!
