[alsa-devel] DMA interrupt not getting triggered(nailed the problem need solution)

Mark in my case it is not restarting the audio stream(though it is trying to call trigger again for restarting) 
because in s3c_snd_lrsync function again i am getting time out(ETIMEDOUT).

iiscon = readl(s3c_i2s.regs + S3C_IISCON);
if (iiscon & S3C_IISCON_LRI)
break;

This LRI register bit is not getting set properly causing timeout.How this situation is not coming always(4/10)??
And who should suppose to set it?

If my machine driver had a problem then this should have come always??

Thanks for your reply.
