Video driver CPU Load - DM6467

Hi TI,

I am using 2.6.18 MVL kernel on DM6467 EVM and doing video capture DQBUF and QBUF only in the system(no file write, no encode, no other activity as such). And i am seeing  around 25% CPU load after 5 minutes.

I also saw that there are similar posts(Even i have posted in those threads) on this issue. However, no one has replied any solution. Do you have any clue on why this should be happening.
