Under normal loads all seems well with my 3c509B, SMP 2.0.35 kernel with 2.0.36pre6 (3c59x.c patch segment only). Under network stress, the box eventually starts spilling "eth0: Re-entering the interrupt handler" messages infinitely at the console and is otherwise unresponsive. Anybody know what this is? Or if there's a fix? many thanks. -jeremy
