I saw the same through CSLIP, so this is then a kernel (not HW) problem (i586/150, UP; gcc-2.95 snapshot for compiling the kernel with -fno-strict-aliasing). The latest 2.2.10-ac10 and 2.3.11-4 don't show it AFAIKS, so I filed that away (no time right now to check into kernel problems). -- Dr. Horst H. von Brand mailto:vonbrand@inf.utfsm.cl Departamento de Informatica Fono: +56 32 654431 Universidad Tecnica Federico Santa Maria +56 32 654239 Casilla 110-V, Valparaiso, Chile Fax: +56 32 797513
