I recently upgraded this machine from 4.x to 5.x and am seeing a lot of watchdog timeouts. I've been trying to track down how to stop the constant watchdog timeouts that I'm experiencing and figured to post to the list. The box is running IPFW and has two NICs. Originally I was using a separate physical Nic (xl0) and after seeing the watchdog timeouts, I switched to a different card. I am now using 2 ports on a quad card and barely pushing traffic through it. Every time I experience a watchdog timeout, packets stall creating chaos for performance. I noticed that it's output errors as opposed to drops. I found a post where someone was talking about problems with getting IRQ resources. From the bootup messages below you can see that I'm seeing errors and again tried to follow other threads where people had the same problems but never got a decent answer. I'm not sure what I can do to fix these problems, but clearly the performance is horrible. Any thoughts? -Troy <snip> from /var/log/messages ============================Mar 3 15:15:55 kernel: dc0: watchdog timeout Mar 3 15:16:11 kernel: dc0: watchdog timeout Mar 3 15:13:49 kernel: dc1: watchdog timeout <hundreds of them> Bootup messages ============== adv1: Invalid baseport of 0x0 specified.
