The only seemingly relevant change I see in the 3c59x driver in the February 
time frame is this one, although the change appears harmless enough:

     NET-3c59x: turn local_save_flags() + local_irq_disable() into local_irq_save

     drivers/net/3c59x.c::poll_vortex() contains local_irq_disable() after
     local_save_flags().  Turn it into local_irq_save().

You might try reverting it to see if it helps.
