So this is a known problem and had already been fixed. Of course, if there are caches with 64 or 128 byte lines, some more work needs to be done. What gives me trouble is the fact that dcbz instruction in function arch/ppc/lib/string.S:__copy_tofrom_user does not seem to work for me. But the function works fine if I remove that instruction. Has anybody else experienced similar problems ? Any suggestions welcome, Daniel Marmier ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
