You could start by doing heavy IO and looking at the wchan of the processes doing IO, to find out where they are sleeping. Then search mm/*.c and fs/*.c for similar functions. > Is there another way to this task? Yes, but the other ways are all harder ;) -- "Debugging is twice as hard as writing the code in the first place. Therefore, if you write the code as cleverly as possible, you are, by definition, not smart enough to debug it." - Brian W. Kernighan -- Kernelnewbies: Help each other learn about the Linux kernel.
