A spot of weirdness I ran into on my e1000 card. It's the 82566DC model [8086:104b] (rev 02) x1 PCIe. After modprobe e1000, ethtool reports that there is no link, despite the correct link lights on the port. This breaks booting during a boot process = that checks for actual link status before using a device. modprobe e1000: > Intel(R) PRO/1000 Network Driver - version 7.2.9-k4-NAPI > Copyright (c) 1999-2006 Intel Corporation. > ACPI: PCI Interrupt 0000:00:19.0[A] -> GSI 20 (level, low) -> IRQ 20 > PCI: Setting latency timer of device 0000:00:19.0 to 64 > e1000: 0000:00:19.0: e1000_probe: (PCI Express:2.5Gb/s:Width x1) 00:16:76= :a3:6c:4d > e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection > ADDRCONF(NETDEV_UP): eth1: link is not ready > ADDRCONF(NETDEV_UP): eth1: link is not ready Now I force the link up with ifconfig: > e1000: eth1: e1000_watchdog: NIC Link is Up 1000 Mbps Full Duplex > ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready This behavior differs from every other network card, and is also present in= the 7.3* version of the driver from sourceforge. I think the e1000 should try to raise the link during the probe, so that it works properly, without having to set ifconfig ethX up first. --=20 Robin Hugh Johnson E-Mail : robbat2@gentoo.org GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85 --O8/n5iBOhiUtMkxf Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Robbat2 @ Orbis-Terrarum Networks iD8DBQFFTpCJPpIsIjIzwiwRApXOAKDC30PMRhS1On4qjtCRepRISIYtugCgue7V D/QRVsC/nswXV1PinOTAIzE= =p68i -----END PGP SIGNATURE----- --O8/n5iBOhiUtMkxf-- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
