mmcqd cpu utilization

Hi,

Has anyone monitored the cpu utilization percentage when a MMC/SD card is in
use? I have noticed that mmc_queue_thread "mmcqd" consumes a lot of cpu
cycles in a periodic fashion. What I mean here is that I see spikes of high
cpu utilization due to mmcqd. There will a cp or similar which will be
already consuming cpu to transfer data to the MMC/SD device. Further mmcqd
increases that load randomly to a high number.

Has anyone seen similar behavior? Any thoughts?

Regards,
Madhu
