Grab the current kernel.org 2.6 release. I suggest you use dirdiff another recent 2.4 kernel and then analyze the 2.6 stuff as it is different yet. There are countless bug fixes that have gone in over the last 3 years. I sincerely hope you aren't trying to use that old kernel with experimental PPC440 support for production work. > BTW, what's the problem three years ago prompted to > change the code regarding mmucr handling? The problem was that the initial code would crash apps regularly. I put the code out in our development tree at the time since it was taking a long time to find the bug...and you could mostly run a system. The MMUCR was not having the TID set properly during a tlbie() and a couple other spots in head_440.S. -Matt
