Hello my friends. I made a new custom distro based on debian squeeze, but with 2.6.39 kernel, patched with reiser4 (http://downloads.sourceforge.net/project/reiser4/reiser4-for-linux-2.6/reiser4-for-2.6.39-1.patch.gz?r=http%3A%2F%2Fsourceforge.net%2Fprojects%2Freiser4%2Ffiles%2Freiser4-for-linux-2.6%2F&ts=1337035240&use_mirror=ufpr). Trying to copy a folder from a reiser3 partition to a reiser4 partition, I got error messages. Testing my custom kernel with "preemption model" in "Preemptible Kernel", I got these messages: [ 286.945598] ------------[ cut here ]------------ [ 286.945609] kernel BUG at fs/reiser4/block_alloc.c:151!
