--- Comment #1 from [email protected] --- The card is definitely not sending: 1) dev.em.0.queue0.tx_irq is *not* increasing, so no signal from the card that data has been sent 2) hence sysctl dev.em.0.debug=1 shows that TX descriptors avail is decreasing 3) when it drops bellow EM_MAX_SCATTER, em_txeof() is finally called: https://svnweb.freebsd.org/base/releng/10.1/sys/dev/e1000/if_em.c?view=markup#l962 4) em_txoef() examines descriptors and detects that the card has not processed any of them and marks the queue as EM_QUEUE_HUNG: https://svnweb.freebsd.org/base/releng/10.1/sys/dev/e1000/if_em.c?view=markup#l3925 5) The queue status is read and the card reset is performed: https://svnweb.freebsd.org/base/releng/10.1/sys/dev/e1000/if_em.c?view=markup#l2297 -- You are receiving this mail because: You are the assignee for the bug. _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "[email protected]"
