[OMAP-L137 - DMA Linux Driver] : Error interrupt raised with no active error present

$

Hi,

While running my application on a Linux-2.6.18_pro500-da830_omapl1, I am confronted to strange error interrupt from the DMA driver.

The callback dma_ccerr_handler is called but all the error registers associated (EMR, EMRH, QEMR and CCERR) are empty.

Regarding the DMA specification, this case should never happen, but we face it often here.

Any idea why this interrupt occurs ?

Regards,
