The warnings look like i386, exactly what hardware is this? Is your
kernel compiled for SMP or UP?
The warning you're getting is that clean_tree_block expects this block
to be locked, and giving out a warning because it is showing up as
unlocked.
So, hopefully you're on a UP kernel and my test for a locked spinlock is
broken in that config.
