So you may want to give a spin to pre6aa1 and see if it makes any difference, if it makes any difference I'll know what your problem is (see the buffer.c part of the vm-10 patch in pre6aa1 for more details). thanks, Andrea -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
