I am pretty sure. All my servers using the same em chip, on all my 6.1 boxes either UP or SMP i see watchdog timeout, average load of this adapters is 5000 - 6000 interrunpts per second. I have only one box with 5.5 (same task and same platform), but i am not claiming that this is exactly the watchdog problem, it's just very symptomatic in context of discussion. In any case new 6.2 em patch works for me, at least i do not see watchdog timeouts after 48 hours of uptime. By the way the box is connected to 2950 switch, i can't find any problems on cabling. Here is how it looks like on 5.5: Oct 18 05:38:45 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 05:38:50 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 05:39:21 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 05:39:32 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: is alive again Oct 18 05:52:22 ms6 kernel: em0: Link is Down Oct 18 05:55:13 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 05:55:13 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 05:55:44 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 05:55:46 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: is alive again Oct 18 06:01:52 ms6 kernel: em0: Link is Down Oct 18 06:03:54 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 06:03:54 ms6 kernel: em0: Link is Down Oct 18 06:04:01 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 06:16:07 ms6 kernel: em0: Link is Down Oct 18 06:18:16 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 06:21:55 ms6 kernel: em0: Link is Down Oct 18 06:25:12 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 06:25:25 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 06:25:27 ms6 kernel: em0: Link is Down Oct 18 06:25:33 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 06:25:43 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 06:26:10 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: is alive again Oct 18 06:43:12 ms6 kernel: em0: Link is Down Oct 18 06:45:13 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 06:45:44 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 06:46:15 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 06:46:27 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 06:46:28 ms6 kernel: em0: Link is Down Oct 18 06:46:34 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 06:46:46 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 06:47:17 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 06:47:26 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: is alive again Oct 18 07:02:51 ms6 kernel: em0: Link is Down Oct 18 07:04:42 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 07:04:44 ms6 kernel: em0: Link is Down Oct 18 07:04:50 ms6 kernel: em0: Link is up 1000 Mbps Full Duplex Oct 18 07:05:13 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 18 07:05:25 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: is alive again Oct 18 16:40:05 ms6 kernel: receive error 60 from nfs server 206.53.x.x:/usr/home/shared Oct 19 03:55:13 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: not responding Oct 19 03:55:15 ms6 kernel: nfs server 206.53.x.x:/usr/home/shared: is alive again After that date it was rebooted at least three times and i don't see such symptoms any more. > > I feel horrible for both Scott and Jack -- I think there's tons > of people coming out of the woodwork with "ME TOO" comments who > may in fact be suffering from other problems, and are looking for > a scapegoat thread. Just ignore me.
