hi auke, thanks for the details/explanation. > So, obviously this is a very hard issue to solve and we have not yet found a > resolution since the real cause is completely outside of the driver and the > adapter, and in hardware that we do not control. > > We're here trying (still) to come up with a workaround... can never really fix > this issue since it's not Intel hardware. reticent to monkey with my Dom0 -- but understanding your point -- i managed to get my hands on a new drive -- and installed a separate non-xen instance. for that system, here's my step-by-step for a NON-xen demonstration of the issue. bottom line -- problem still exists, whether xen, or non-xen kernel is used details -n- bits: uname -a Linux server.local 2.6.24.3-50.fc8 #1 SMP Thu Mar 20 13:39:08 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux yum install ppp net-tools rp-pppoe kernel-devel gcc lspci | grep -i intel 04:07.0 Ethernet controller: Intel Corporation 82541PI Gigabit Ethernet Controller (rev 05) cd /etc/sysconfig/network-scripts cat /etc/sysconfig/network-scripts/ifcfg-eth0 BOOTPROTO=none DEVICE=eth0 ETHTOOL_OPTS="autoneg on" HWADDR=xx:xx:xx:xx:xx:xx IPV6INIT=no IPV6_AUTOCONF=no MTU=1492 NM_CONTROLLED=no ONBOOT=yes TYPE=Ethernet USERCTL=no cat /etc/modprobe.conf alias eth0 e1000 options e1000 debug=16 XsumRX=0 Speed=1000 Duplex=2 InterruptThrottleRate=0 FlowControl=3 RxDescriptors=4096 TxDescriptors=4096 RxIntDelay=0 TxIntDelay=0 alias eth1 forcedeth alias /dev/ppp ppp_generic alias net-pf-24 pppoe alias char-major-108 ppp_generic alias tty-ldisc-3 ppp_async alias tty-ldisc-14 ppp_synctty alias ppp-compress-18 ppp_mppe alias ppp-compress-21 bsd_comp alias ppp-compress-24 ppp_deflate alias ppp-compress-26 ppp_deflate ... cat /etc/sysconfig/modules/pppoe.modules #!/bin/sh MP="/sbin/modprobe" $MP pppoe $MP ppp_generic $MP ppp_async $MP n_hdlc $MP ppp_synctty $MP ppp_mppe $MP ppp_deflate grep -i ppp /boot/config-`uname -r` CONFIG_PPP=m CONFIG_PPP_MULTILINK=y CONFIG_PPP_FILTER=y CONFIG_PPP_ASYNC=m CONFIG_PPP_SYNC_TTY=m CONFIG_PPP_DEFLATE=m # CONFIG_PPP_BSDCOMP is not set CONFIG_PPP_MPPE=m CONFIG_PPPOE=m CONFIG_PPPOATM=m CONFIG_ISDN_PPP=y CONFIG_ISDN_PPP_VJ=y CONFIG_IPPP_FILTER=y # CONFIG_ISDN_PPP_BSDCOMP is not set modinfo e1000 | grep ^version version: 7.3.20-k2-NAPI cd /tmp/e1000-7.6.15.5/src make install ls -al /lib/modules/2.6.24.3-50.fc8/kernel/drivers/net/e1000/e1000.ko -rw-r--r-- 1 root root 3217601 2008-03-28 11:17 /lib/modules/2.6.24.3-50.fc8/kernel/drivers/net/e1000/e1000.ko rmmod e1000 insmod /lib/modules/2.6.24.3-50.fc8/kernel/drivers/net/e1000/e1000.ko modinfo e1000 | grep ^version version: 7.6.15.5-NAPI cat /etc/ppp/pppoe.conf ACNAME= CLAMPMSS=1412 CONNECT_POLL=6 CONNECT_TIMEOUT=60 DEFAULTROUTE=yes DEMAND=no DNSTYPE=SERVER ETH=eth0 FIREWALL=NONE LCP_FAILURE=3 LCP_INTERVAL=20 LINUX_PLUGIN= PEERDNS=no PIDFILE=/var/run/pppoe-adsl.pid PING="."
