It's not enough that forcedeth's interrupts are disabled, local cpu interrupts have to unconditionally be off when we remove the device from the poll list. Based upon a crash report from Alexander Beregalov <a.beregalov@gmail.com>: WARNING: at lib/list_debug.c:30 __list_add+0x89/0x90() Hardware name: list_add corruption. prev->next should be next (c06ea834), but was f70244c8. (prev=c06ea834).
