Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org When I compile a non-modular 2.6 kernel for ppc with gcc-3.3.1, it oopses in __copy_tofrom_user() [copy_mount_options()] in user-space's first mount /proc call. User-space limps along for a while, oopsing in every mount call, and then hangs. This occurs with 2.6.0-test5, test6, and the test7-based linuxppc-2.5 tree (rsync:ed today). Enabling CONFIG_MODULES=y but still keeping everything built-in prevents the oopses. With gcc-3.2.3 there are no problems. I don't have a serial console to the ppc box (weird mac serial port), but I can try to manually type down and decode the first oops if necessary. /Mikael
