Stig-Arne Grönroos, thank you for reporting this and helping make Ubuntu better. As per https://downloadcenter.intel.com/SearchResult.aspx?lang=&ProductID=3284&ProdId=3284 an update to your BIOS is available (0160). If you update to this following https://help.ubuntu.com/community/BiosUpdate does it change anything? If it doesn't, could you please both specify what happened, and provide the output of the following terminal command: sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date
Please note your current BIOS is already in the Bug Description, so posting this on the old BIOS would not be helpful. As well, you don't have to create a new bug report. As well, you don't have to create a new bug report. For more on BIOS updates and linux, please see https://help.ubuntu.com/community/ReportingBugs#Bug_reporting_etiquette . Once the BIOS is updated, then please mark this report Status Confirmed. Thank you for your understanding. ** Tags added: bios-outdated-0160 ** Changed in: linux (Ubuntu) Importance: Undecided => Low ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1352461 Title: IRQ conflict disables wired network on cold (first) boot Status in “linux” package in Ubuntu: Incomplete Bug description: On every cold boot the ethernet controller fails to load, leaving the wired network completely disabled. No interface /dev/eth0 is created. IRQ 49 is taken by snd_hda_intel. 49: 29219 0 0 0 PCI-MSI-edge snd_hda_intel eth0 is not listed in /proc/interrupts The following log message is printed: e1000e: probe of 0000:00:19.0 failed with error -3 When rebooting the machine (without powering down), the ethernet controller loads normally and functions without problems. IRQ:s are now allocated differently: 49: 155107 0 0 0 PCI-MSI-edge eth0 50: 1414 965740 0 0 PCI-MSI-edge snd_hda_intel The expected behaviour is that the ethernet controller will be assigned an IRQ on the first boot, and load normally. The network controller worked fine in Precise, until some upgrade in June. I did not diagnose the problem immeditaly, and don't know which upgrade caused the regression. Upgrading to Trusty (Ubuntu 14.04.1 LTS) did not solve the problem. The problem is not random: it occurs at every cold boot and the workaround of rebooting immediately after each cold boot works persistently. I tried, as a workaround, setting the following kernel parameters (one at a time): pci=noacpi , pci=routeirq , noapic, acpi=off, pcie_pme=force and irqpoll None of the listed kernel parameters affected the problem. rmmod e1000e followed modprobe e1000e didn't help. The ethernet controller is a 00:19.0 Ethernet controller: Intel Corporation 82579V Gigabit Network Connection (rev 05) Kernel driver in use: e1000e The sound chip is a 00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset Family High Definition Audio Controller (rev 05) Kernel driver in use: snd_hda_intel Both of the devices are on-board chips on the motherboard, so changing slots is not possible as a workaround.
