Hello everybody,
I've been getting some strange errors with this dual port nic. My
system is a dual core AMD64 system running 4.1-stable with
multiprocessor support enabled. The chipset of the card is 82571EB.
This problem also occurs when I boot into a kernel without MP support.
em0 works fine, but em1 throws watchdog timeout errors frequently, and
it is so slow to the point of being unusable. em1 is slow even if it
happens to not be throwing the watchdog timeout errors. I first
noticed this when i set both devices to configure via dhcp. Thinking
it might be a broken card, I swapped in another card of the same model
and chipset, and experienced the same problem. The other nic in the
system, re0, works fine. I've looked through some message boards on
the subject but I have not found anything conclusive, and I'm at a
loss at what the problem could be. I'm hoping it's a configuration
issue, or a problem at my end. Any advice would be greatly appreciated.
Bob,
I've seen problems and watchdog timeout messages with the Intel em
driver too. Henning Brauer and Mark Kettenis corrected the em driver and
the cards now work properly.
The current drivers (in src/sys/dev/pci/if_em*) will probably work with
4.1 but Henning and Mark are the ones to ask for more details.
