stef.baly, to advise, you don't need to apport-collect further unless requested to do so. Especially with the mainline kernel installed as the information is useless.
Despite this, could you please test the latest upstream kernel available from the very top line at the top of the page from http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D (the release names are irrelevant for testing, and please do not test the daily folder)? Install instructions are available at https://wiki.ubuntu.com/Kernel/MainlineBuilds . This will allow additional upstream developers to examine the issue. If the latest kernel did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this issue is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-X.Y-rcZ Where X, Y, and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix the issue, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-X.Y-rcZ Please note, an error to install the kernel does not fit the criteria of kernel-bug-exists-upstream. Once testing of the latest upstream kernel is complete, please mark this report's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Attachment removed: "ProcEnviron.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492850/+attachment/4496092/+files/ProcEnviron.txt ** Attachment removed: "JournalErrors.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1492850/+attachment/4496091/+files/JournalErrors.txt ** Tags removed: bios-outdated-a16 ** Tags added: latest-bios-a16 ** Description changed: I try for a long time to set-up the wifi for my dell pro venue 11 v7130 (wifi chipset Intel Corporation Wireless 7260). The wifi connection is perfect until the computer is suspend. After a suspend, even activating the wifi from network manager is impossible. After suspend even an exit doesn't reconnect to the wifi connection. It seems that the wifi chipset is off and it's impossible to wake up. Recently 15.04 has been update to 4.2 RC8. Nothing new ! A file unload_modules has been created. /etc/pm/config.d with SUSPEND_MODULES="$SUSPEND_MODULES iwlwifi" without any effect. sudo service network-manager restart doesn't work too !
