[-- Attachment #1 --] Hello all, I am receiving kernel panics under 4.3-RC #0 when trying to bring up PPPoE. A copy of the kernel debug, the start up and the actual PPP configuration are attached. It appears to be something in the subroutine called fxp_start of the actual ethernet card (Which is an Intel Express) trying to use a structure which has not yet been initialized. The machine is an SMP machine as well; although compiling without SMP support has so far made no difference. The problem also occurs under 4.2-RELEASE. Any help on the subject would be appreciated. -- Snowy Angelique Maslov aka Snowpony My..
