I wonder if the fact that I use "suspend freeze" mode instead of default "suspend" mode makes a difference? https://www.freedesktop.org/software/systemd/man/sleep.conf.d.html
I have to do so because modern hardware implement S0i3 instead of S3, so default mode will just won't work (tablets and laptops without S3 support will just poweroff or reboot on attempt to go into S3). > I'll analyze the logs and let you know what I find. Ok. Just to let you know, I find first unit not reliable enough, so I edited it a little bit: Removed "StopWhenUnneeded=yes" and "RemainAfterExit=yes". Replaced "=-/bin/systemctl" with "=/bin/systemctl". -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to modemmanager in Ubuntu. https://bugs.launchpad.net/bugs/1326954 Title: Sierra Wireless EM7305 (Fujitsu Lifebook S904) does not work after suspend/hibernate Status in ModemManager: Unknown Status in libmbim package in Ubuntu: Confirmed Status in modemmanager package in Ubuntu: Invalid Bug description: Ubuntu 14.04, x86_64, ModemManager-1.0.0-2ubuntu1 Card: Sierra Wireless EM7305 (PCI Express M.2 form factor) Expected: Sierra plugin is used Happens: Generic plugin is used instead After cold start the card seems to work almost fine, but does not come back after suspend or hibernate.
