It looks like it is indeed a power management issue. Last threee days I made and manually run this script when I login; seba@D630:~$ cat $HOME/bin/iwl_power_save.sh sudo iw dev wlp12s0 get power_save sudo iw dev wlp12s0 set power_save off sudo iw dev wlp12s0 get power_save
and I haven't had any issue. Everytime I boot power management is on and I switch it off. I will report in a week. Maybe I will also switch back to the HWE kernel to make sure this is reproducible with the ubuntu kernel. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1627828 Title: iwl3945 crashes randomly To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1627828/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
