I'm running a RELENG_7/amd64 as of 2008-Feb-22 with the re(4) driver from the URLs above. As a precaution, I disabled all kinds of hardware offloadings. | # grep ^ifconfig_re.= /etc/rc.conf | ifconfig_re0="inet x.x.x.x netmask 255.255.255.224 media auto -rxcsum -txcsum -tso -lro -vlanhwtag" | # ifconfig re0 | re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 | options=88<VLAN_MTU,VLAN_HWCSUM> | ether 00:1d:92:x:x:x | inet6 fe80::21d:92ff:fexx:xxxx%re0 prefixlen 64 scopeid 0x1 | inet x.x.x.x netmask 0xffffffe0 broadcast 78.46.41.63 | inet x.x.x.x netmask 0xfffffff8 broadcast 78.47.124.7 | inet x.x.x.x netmask 0xfffffff8 broadcast 78.47.124.7 | inet x.x.x.x netmask 0xfffffff8 broadcast 78.47.124.7 | inet x.x.x.x netmask 0xfffffff8 broadcast 78.47.124.7 | inet x.x.x.x netmask 0xfffffff8 broadcast 78.47.124.7 | inet x.x.x.x netmask 0xfffffff8 broadcast 78.47.124.7 | media: Ethernet autoselect (100baseTX <full-duplex>) | status: active | # pciconf -lv [...] | re0@pci0:2:0:0: class=0x020000 card=0x368c1462 chip=0x816810ec rev=0x01 hdr=0x00 | vendor = 'Realtek Semiconductor' | device = 'RTL8168/8111 PCI-E Gigabit Ethernet NIC' | class = network | subclass = ethernet [...] After almost one week uptime, the machine is still stable.
