I have a server with the same chipset. amd I've been dealing with problems ever since. This relates to a known bug in the drivers for this card. A fix has been posted back in October last year....
http://userweb.kernel.org/~romieu/r8169/2.6.27-rc9/20081007/0009-r8169-fix-RxMissed-register-access.patch Its a shame that no-one has integrated this into the official Centos kernel code yet. I also have a server with this problem. Rather than running custom unsupported kernels, I have a small script that runs to detect and recover from the problem. Basically, it pings the default gateway. If the response time is greater than 50 msec on average, it does a ifdown / ifup for that interface. I run this every 15 minutes in /etc/cron.quarter-hourly Regards, Greg. #!/bin/bash MAXPING=50 MYIF=`route -n | grep ^0.0.0.0 | cut -b 73- | tail -1` MYGW=`route -n | grep ^0.0.0.0 | cut -b 17- | cut -d " " -f 1 | tail -1` PINGTIME=`ping $MYGW -A -c 5 | grep "/" | cut -d "/" -f 5 | cut -d "." -f 1` if [ $PINGTIME -gt $MAXPING ] then echo Refreshing interface $MYIF ifdown $MYIF ifup $MYIF fi -- +---------------------------------------------------------------------+ | / \ Greg Kuhnert, [email protected] | | < o > Compass Networks - Pointing you in the right direction | | \ / Come see us for BlueQuartz / BlueOnyx modules & Support. | +---------------------------------------------------------------------+ Stephanie Sullivan wrote: >> -----Original Message----- >> From: [email protected] [mailto:blueonyx- >> [email protected]] On Behalf Of User Ernie >> Sent: Wednesday, November 25, 2009 8:13 PM >> To: [email protected] >> Subject: [BlueOnyx:02946] Suspected Ethernet problem with r8169 >> driver >> >> I am having a strange problem with bueOnyx on an Intel Atom D945GCFL2 >> mini-itx board and the r8169 ethernet controller.
