You can see the same phenomenon in the tarball that Narinder posted above. Here's the em3 definition at the time em1 appeared: BIOS device: em3 Kernel name: em3 Permanent MAC: 00:17:A4:77:3C:08 Assigned MAC : 00:17:A4:77:3C:08 ifIndex: 4 Driver: be2net Driver version: 4.2.220u Firmware version: 4.1.450.7 Bus Info: 0000:04:00.2 PCI name : 0000:04:00.2 PCI Slot : embedded Embedded Index: 3
And then at the time em2 appeared: BIOS device: em3 Kernel name: em5 Permanent MAC: B4:99:BA:A6:B9:18 Assigned MAC : B4:99:BA:A6:B9:18 ifIndex: 6 Driver: be2net Driver version: 4.2.220u Firmware version: 4.1.450.7 Bus Info: 0000:04:00.4 PCI name : 0000:04:00.4 PCI Slot : embedded SMBIOS Device Type: Ethernet SMBIOS Instance: 5 Embedded Index: 5 As you can see above, the same BIOS entry "em3" switched mac address and now refers to a completely different NIC. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1090002 Title: biosdevname gives name of device as rename7 in Quantal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1090002/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
