Bug 133750

Description of problem:

When I try to write multitrack audio CD it fails with OOM. Writing one
track data CD works ok.

My configuration:
RAM 128MB
ATAPI CD-RW Teac CD-W54E (firmware 1.1Y)

Notes: It doesn't depend on whether I write it using cdrecord or
cdrdao. It happens with FC2 stock versions of cdrdao and cdrecord as
well. It doesn't matter if I write single .bin image or multiple .wav
files. It doesn't depend on swap size or if there is no swap at all.
But it doesn't happen on the box with 512MB of RAM with USB CD/DVD-RW
drive.

Version-Release number of selected component (if applicable):

kernel-2.6.8-1.521
cdrdao-1.1.9-5
cdrecord-2.01.1-2

How reproducible:

Always (but see above notes)

Steps to Reproduce:
1. Make sure you have 128MB of RAM and ATAPI CD-R/RW drive
2. Create an image of multitrack audio CD or rip it into .wav files
3. cdrdao write --device ATAPI:0,0,0 image.toc
  
Actual results:

After writing about 266-268MB and 5 tracks the buffers drop from 100%
to 81% and then OOM killer killed it.

Expected results:

It should write it to the end.

Additional info:

It worked before on 2.4.x kernel series. And there are suspicious
messages from the kernel about DMA memory.
