The following reply was made to PR kern/15542; it has been noted by GNATS. From: Michael Glasgow <glasgow@beer.net> To: bug-followup@FreeBSD.org, ap@bnc.net Cc: Subject: Re: kern/15542: de suddenly stops working Date: Mon, 20 Jun 2005 13:33:27 -0500 (CDT) I'm seeing similar behavior on 5.1-RELEASE-p7, with a quad-port (ZNYX ZX34X 21140A [10-100Mb/s] pass 2.2) using the de driver. For me, it's not repeatable, but I'll see the occasional message like this: May 2 13:59:06 hostname kernel: de1: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) May 4 20:49:32 hostname kernel: de3: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) May 5 00:12:27 hostname kernel: de1: abnormal interrupt: transmit underflow (raising TX threshold to 128|512) May 5 01:08:24 hostname kernel: de2: abnormal interrupt: transmit underflow (raising TX threshold to 96|256) And only occasionally (rarely) does the NIC lock up and stop sending or receiving packets. Often there is some time between the last of these messages and when the NIC stops working, for example the last lockup happened approx 17-Jun-05 22:00, but nothing was logged after the message on May 5 above.
