Argh! That's all because of the CONFIG_NETPOLL_TRAP that CONFIG_KGDBOE*
options select -- since the initial breakpoint enables trapping via KGDBoE's
pre_exception() handler, netif_{stop/wake}_queue() stop to work and that
causes KGDBoE to literally flood 8139too with packets (although it can't queue
up more than 4). Looks like a general design issue to me... :-/
WBR, Sergei
