We have upgraded the BIOS of the machine: # sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date A18 04/30/2014
We now find that after a reboot, the first suspend and resume cycle takes long: after pressing enter in the password screen it takes about 60 seconds to either log that the password is incorrect or that the system logs in. Every subsequent suspend/resume cycle after that is just a couple of seconds. -- 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/1352379 Title: Network broken after resume Status in “linux” package in Ubuntu: Incomplete Bug description: We use Dell Optiplex 7010 machines in our student lab. These machines are capable of suspending and resuming, so that we don't waste power during the night. In our lab we also use LDAP authentication for the students. The problem is that networking is disabled once the machine is resumed after a suspend. Because of the LDAP authentication, networking is required for authentication, thus we cannot login to the machine after a suspend. A "work-around" to restart network-manager is therefor not an option. I have tried numerous things, * creating a file /etc/pm/config.d/network-resume with the content "SUSPEND_MODULE="e1000e" Outcome: This seems to break the suspend functionality. When manually entering "suspend" it goes directly to the lock screen. The networking is still disabled, so I cannot log in. * creating a file /etc/pm/sleep.d/network-resume with #!/bin/sh case ${1} in resume|thaw) nmcli nm sleep false ;; esac Outcome: Manually suspending works, resume only works when pressing the power button. Once resumed the networking is still disabled, and thus I cannot log in. * creating a file in /etc/pm/sleep.d with #!/bin/sh case "${1}" in resume|thaw) restart network-manager ;; esac Outcome: Manually suspending works, resume only works when pressing the power button. Once resumed the networking is still disabled, and thus I cannot log in. After about a full minute networking is restored and I can log in. --- ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: lightdm 1285 F.... pulseaudio DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=5f5a9253-499b-4d0a-a0ea-903335a5222f InstallationDate: Installed on 2014-07-08 (27 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) IwConfig: eth0 no wireless extensions. lo no wireless extensions.
