None, but things like this are related to acpi issues often enough to make some boot time acpi options worth trying. Also: try booting the smp kernel with the "nosmp" option. That's not the same as the uni kernel, and might aid in telling unhappy kernel from unhappy hardware. -- bill davidsen CTO TMR Associates, Inc Doing interesting things with small computers since 1979
