Hi bonsiware, I cannot confirm, but after installing a new firmware on the TS-632D DVDRW drive which I found on http://www.toshibaer.com/firmware/index.php?path=TS-L632D/ those ata timeouts completely disappeared on my Aspire 9412AWSMi, so I suppose this is not a kernel bug, but rather was a firmware bug.
I found out that my DVDRW drive had revision AC00 on it, the bin file in the zip file is revison AC01. I used TS-L632D_AC01_Acer_OEM.zip You need Windows to flash the firmware, though. Be aware that flashing a new firmware on your DVDRW drive may destroy it if flashing fails or you flash a wrong firmware.
