Social stuff:

GRRRR: That's no reason to call MTD unstable, if you have to modify some code. 

Do you think Open Source is a no cost self service restaurant, where you can 
whistle for the waiters ? If there has something to be fixed, provide either 
sufficient information or a patch, which fixes this problem. Keep in your 
mind, that 5 lines of your code and 1 hour of your work you could be your 
share of 10000000 lines of code and hundreds of men years work of others, who 
don't complain if there is something to fix and are all willing to help 
others, if they are asked nicely and the neccecary information is provided.

Statements like the above are nothing else than FUD and will just degrade the 
willingness of people to help you.

Technical stuff:

Where does the compile _exactly_ fail ? Which version of MTD _excactly_ ? How 
did you patch your kernel _exactly_ with MTD ?
