The commit I am referring to is:
http://git.denx.de/?p=ipipe-2.6.git;a=commit;h=b1947dc2ed54e0f838965918dbb36cf8c8d97fb6
Which took place in the 2.6.29 development branch. In 2.5.1, you should
not see the bug if you are compiling with unlocked context switches.
I made a public announce for the same problem on ARM, but not for powerpc.
