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 from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
