Understood. That makes sense. In fact, your problem is most likely *not* 
related to this commit. As I mentioned before, please try narrowing down 
what specifically caused this; if I read correctly, you jumped from 
2.6.33 to 2.6.36-rc1. There have been several important changes between 
those releases. Notably, this commit may be giving Samsung chips problems:
426c457a3216fac74e

This thread is covering a few problems with Samsung:

Unless you really know what you're doing, I wouldn't be writing/erasing 
the flash if it's not detecting bad blocks properly.

Let me know if you have trouble with narrowing down to the problem commit.
