Some more observations working on the Issue, when the NIC is working lspci reports it has the "bus master" flag, MSI is enabled, and IRQ typically 46. When not working lspci reports no "busmaster", MSI is disabled, and IRQ is 20. Syslog always reports e1000e looking at IRQ 46. In the failure case, the card remains unclaimed and the mei driver claims IRQ 46.
This raises two questions: 1) Why do the settings change and are both valid? 2) Why does e1000e always report IRQ 46 when lspci reports IRQ 20? Any ideas on how to investigate further? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1072722 Title: 8086:294c Intel NIC driver e1000e not claiming HW To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1072722/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
