PXA270 audio problem

Hi,
The problem persists in the linux kernel 2.6.35.7 as well. If I
repeatedly play a set of mp3 files continuously the audio stops after
some time with the following error:
ALSA sound/core/pcm_native.c:1512: playback drain error i(DMA or IRQ trouble?)
The DMA interrupts stop occuring. But the DMA interrupts does occur
for audio record in this state and the touch screen works.
One thing I have noticed is if I remove and insert back the
snd_pxa2xx_ac97 module, audio playback starts again. But the touch
screen stops working from there on. I need to reboot the machine.
I tried exploring the DMA operation for audio playback. I noticed that
on reaching the no audio playback state the REQPEND bit of DCSR
register stops getting set after the DDADR is loaded with the address.
I have attached the files having dumps at various stages of audio
playback. The change in DMA register settings can be noticed in the
line having "START DMA->".
I am now exploring the AC97 communication part. Some times I doubt if
it is a bug in the processor. But still no proper justification yet.
Warm regards,
Santhosh N
