Thaks this could be a problem. I have changed
- wait_for_completion_interruptible(&(device->wfc)); + wait_for_completion_interruptible_timeout(&(device->wfc), ); But with any success it hung somewhere else. However I will check the H3A Print /proc/interupts is impossible, because when it hungs, it hungs totaly. I have no way to do anything. Only to restart whole system.

As far as I remember, there was some issue with the H3A and previewer. When H3A is enabled, previewer stops giving interrupts. Can you check whether previewer interrupts are coming properly? You can check it by printing /proc/interrupts file. There should an entry for the previewer in this file and it should be incrementing if interrupts are coming properly. If interrupt is not coming, previewer will wait for the interrupt and will not come out of it Thanks, Brijesh Jadav From:davinci-linux-open-source-boun...@linux.davincidsp.com [mailto:davinci-linux-open-source-boun...@linux.davincidsp.com] On Behalf OfOndrej Pindroch Sent: Monday, July 06, 2009 7:47 PM To: davinci-linux-open-source Subject: LSP 2.10 Previewer hung on preview task Hi Do someone have tested davinci_previewer from LSP 2.10 on DVEVM DM6446. I have made one test with one frame and all was ok. But when use previewer for stream from MT9P031 board. It hung on IOCTL - PREV_PREVIEW. I have put some printk() in driver.
