I have updated the bios. I have a windows partition on the machine and I booted windows and downloaded the bios update from http://support.hp.com /us-en/drivers/selfservice/HP-Pavilion-HPE-h8-1300-Desktop-PC- series/5258496/model/5261720 and installed it under windows. (this broke grub, but I can deal with that)
I still have the same issue - ethernet works if I fall back to 3.19.0-16-generic, but not with 3.19.0-18 mark@msapiro:~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date 8.21 10/20/2014 mark@msapiro:~$ ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1458208 Title: AR8161 ethernet stopped working after upgrade from 3.19.0-16 to 3.19.0-18 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1458208/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
