That looks pretty funky, most processes are stuck waiting for IO or waiting for
others to finish their IO (on inode->i_mutex). If you switch to another IO
scheduler, does the problem go away? To do so, do:

# echo deadline > /sys/block/sda/queue/scheduler

(or use sdb, if that is the device in question) and repeat your find/du run.
