If you do a dmesg are you also showing a watchdog time out for the nic ?
I only ask as I am having the exact same problem with the exact same
card and I have yet to find a solution, if I come across something I
will let you know.

Graeme
Not a single time...sorry.

Hi everyone,
Just to put you in context, I applied the following patch to make the
card available:
SVN rev 186389 on 2008-12-22 00:46:22Z by yongari
Since we don't request reset for rlphy(4), the link state 'UP'
event from mii(4) may not be delivered if valid link was already
established. To address the issue, check current link state after
driving MII_TICK. This should fix a regression introduced in
r185753 on fast ethernet controllers.
---
I don't have any issue related to that anymore. The problem is that I
get link UP/DOWN a few times per hour on 3 identical machines that I
dumped/restored. They are all pluged in a Cisco switch that works
fine for every other PCs.
Jan 26 06:09:15 term005 kernel: re0: link state changed to DOWN
Jan 26 06:09:17 term005 kernel: re0: link state changed to UP
I tried to switch cables, but I got the same result.
There is the pciconf -lv output:
r...@pci0:3:0:0: class=0x020000 card=0x02831028 chip=0x816810ec
rev=0x02 hdr=0x00
vendor = 'Realtek Semiconductor'
device = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC'
class = network
subclass = ethernet
There is the output of vmstat -i:
interrupt total rate
irq18: re0 ehci0++ 63766 0
irq19: atapci0 277001 3
cpu0: timer 156068748 1961
Total 156409515 1966
Could it be related to the fact that there is re0 and ehci0++ on the
same IRQ?
Thank you for your help,
Martin
I just tried with a brand new Dell 2708 switch and the problem is
still there. I just confirmed that the UP/DOWN occurs every 10 minutes
(+- a few seconds).
Thanks again,
Martin
Just to follow-up on my own problem...
I tried to disable some options of the card with :
ifconfig re0 -rxcsum -txcsum -tso -lro -vlanhwtag
but nothing as changed. I just tried to download a big file (FreeBSD
7.1-REL DVD iso in fact) to see if the deconnection occurs even during a
transfer. The DVD downloaded successfully and I verified that the MD5
are OK. BUT, /var/log/messages continue to tell me that:
Feb 4 16:09:29 term003 kernel: re0: link state changed to UP
Feb 4 16:19:26 term003 kernel: re0: link state changed to DOWN
Feb 4 16:19:30 term003 kernel: re0: link state changed to UP
Feb 4 16:19:32 term003 kernel: re0: link state changed to DOWN
during the transfer (which worked OK). I don't know if that can help
someone to help me ;)
Thanks,
Martin

I have a solution to this well a work around.
Add -tso to the relevant line in /etc/rc.conf
ifconfig_re0="inet 192.168.1.103 netmask 255.255.255.0 -tso"
Adding -tso stops the link up / link down problem. Now I am understand that
this may increase cpu if the traffic on the nic is high. I am sure some one the
list will know of any other implications this may have.
It is a known problem and I site I read the bug had been submitted so hopefully it wont exist in 8.0
Regards
Graeme
As I stated in my last post, I tried to disable a few options, including
TSO. Still, I gived a try to your workaround. I now have this line in
rc.conf:
ifconfig_re0="DHCP -tso"
but I have the same problem (it disconnect every 10 minutes and ask for
an IP to the DHCP).
Thanks for your suggestion,
Martin
