I've recently upgraded my 6.0-STABLE machine to 6.1-STABLE, and since the upgrade i'm getting "em0: watchdog timeout -- resetting" messages every once in a while (sometimes twice a day, sometimes every couple of days).

I doubt this is an issue of unlogged events now being logged, as I also see stalls in traffic when those timeouts occur, a thing i didn't have before. ________________________________ From: Gleb Smirnoff [mailto:glebius@FreeBSD.org] Date: × 15/09/2006 18:35 To: Imri Zvik CC: freebsd-gnats-submit@FreeBSD.org Subject: Re: kern/103256: em0: watchdog timeout -- resetting (6.1-STABLE) On Thu, Sep 14, 2006 at 08:46:08AM +0000, Imri Zvik wrote: I> >Environment: I> FreeBSD wintergreen 6.1-STABLE FreeBSD 6.1-STABLE #1: Wed Aug 30 09:54:35 IDT 2006 root@wintergreen:/usr/obj/usr/src/sys/IGLD i386 I> >Description: I> I've recently upgraded my 6.0-STABLE machine to 6.1-STABLE, and since the upgrade i'm getting "em0: watchdog timeout -- resetting" messages every once in a while (sometimes twice a day, sometimes every couple of days).

Sorry for the scrambled (base64 encoded) text. Here is my original reply: I doubt this is an issue of unlogged events now being logged, as I also see stalls in traffic when those timeouts occur, a thing I did not have before.

Hi, I have not tried it yet. This is a production machine, so I will have to wait for the next maintenance window (as this can only be set at boot time). I will update the PR as soon as I can apply this change.

Hello, I can confirm this problem on an SMP amd64 machine (Core 2 Duo, Supermicro PDSMI+ motherboard) with built-in Intel 82573V and 82573E PCI-Express gigabit NICs and an Intel 82545GM PCI-X gigabit card. Both 6.1 and 6.2-BETA1 exhibit the same behavior: starting a download (e.g., portsnap fetch) is enough to trigger the timeout and a loss of connectivity on the PCI-E NICs, but not the PCI-X one. The 82545GM card works fine without debug.mpsafenet=0, but the 82573s will only work with debug.mpsafenet=0. I have several of these servers which are not in production, so I can test whatever patches may be necessary.

Having same problem here with 6.2-RELEASE-p4 stock SMP-kernel on a SuperMic= ro SuperServer 50145M-MT+ with IPMI module. Connected at a gigabit switch with Category 6 cable. Tried another cable an= d a 100Mbit/s switch with same result. Now trying out sysctl dev.em.0.tx_int_delay=3D0 Please let me know if I can provide further info. --------------- ws# grep em0 messages Jun 27 07:59:56 ws kernel: em0: watchdog timeout -- resetting Jun 27 07:59:56 ws kernel: em0: link state changed to DOWN Jun 27 07:59:59 ws kernel: em0: link state changed to UP Jun 27 08:01:00 ws kernel: em0: watchdog timeout -- resetting Jun 27 08:01:00 ws kernel: em0: link state changed to DOWN Jun 27 08:01:03 ws kernel: em0: link state changed to UP Jun 27 08:09:14 ws kernel: em0: watchdog timeout -- resetting Jun 27 08:09:14 ws kernel: em0: link state changed to DOWN Jun 27 08:09:17 ws kernel: em0: link state changed to UP Jun 27 08:14:51 ws kernel: em0: watchdog timeout -- resetting Jun 27 08:14:51 ws kernel: em0: link state changed to DOWN Jun 27 08:14:54 ws kernel: em0: link state changed to UP Jun 27 08:26:00 ws kernel: em0: watchdog timeout -- resetting Jun 27 08:26:00 ws kernel: em0: link state changed to DOWN Jun 27 08:26:03 ws kernel: em0: link state changed to UP Jun 27 08:31:22 ws kernel: em0: watchdog timeout -- resetting Jun 27 08:31:22 ws kernel: em0: link state changed to DOWN Jun 27 08:31:25 ws kernel: em0: link state changed to UP Jun 27 09:03:28 ws kernel: em0: watchdog timeout -- resetting Jun 27 09:03:28 ws kernel: em0: link state changed to DOWN Jun 27 09:03:31 ws kernel: em0: link state changed to UP Jun 27 09:08:47 ws kernel: em0: watchdog timeout -- resetting Jun 27 09:08:47 ws kernel: em0: link state changed to DOWN Jun 27 09:08:50 ws kernel: em0: link state changed to UP Jun 27 09:17:26 ws kernel: em0: watchdog timeout -- resetting Jun 27 09:17:26 ws kernel: em0: link state changed to DOWN Jun 27 09:17:29 ws kernel: em0: link state changed to UP Jun 27 09:18:01 ws kernel: em0: watchdog timeout -- resetting Jun 27 09:18:01 ws kernel: em0: link state changed to DOWN Jun 27 09:18:04 ws kernel: em0: link state changed to UP Jun 27 09:18:29 ws kernel: em0: watchdog timeout -- resetting Jun 27 09:18:29 ws kernel: em0: link state changed to DOWN Jun 27 09:18:32 ws kernel: em0: link state changed to UP Jun 27 09:19:02 ws kernel: em0: watchdog timeout -- resetting Jun 27 09:19:02 ws kernel: em0: link state changed to DOWN Jun 27 09:19:05 ws kernel: em0: link state changed to UP --------------- ws# uname -a FreeBSD ws.inter-data.dk 6.2-RELEASE-p4 FreeBSD 6.2-RELEASE-p4 #0: Thu Apr = 26 17:55:55 UTC 2007 root@i386-builder.daemonology.net:/usr/obj/usr/src= /sys/SMP i386 --------------- ws# cat /var/run/dmesg.boot Copyright (c) 1992-2007 The FreeBSD Project.

Sorry - misread earlier postings. Trying out /boot/loader.conf with debug.mpsafenet=3D"0" Seems to solve it so far (but only been testing for 30 minutes) Let me know what I can do to help solving this issue
Solved my problem by updating wrong eeprom register with intel utility as d= escribed here: http://www.higherorder.com.au/2007/6/25/intel_82573_patch This does not look like a FreeBSD bug. More like a hardware bug?
This should be repaired by recent changes to watchdog handling in em(4) that are targetted for the 10.2r release. Please retest if possible with the 10.2r beta when available and start a new ticket if not fixed.
I still getting this with my 10.3r-amd64
