OK, I've had time to triage wifi-debug (sorry, but I'm sure you understand!), and it is now running. This failure takes between a few minutes to several hours to emerge; I will almost certainly see wifi dropouts in the next few hours, but it may or may not lose association entirely for a very long time. We shall see. If I have a rocky patch I'll go ahead and send the log, and if that's not sufficient we'll try to make sure to get a total association loss.
Regarding kernel versions; it sounds like you'd like me to test 3.14 (current) as well as 3.15-rc2 and 3.15-rc3? To clarify, 3.15-rc3 worked without any issues for several days, so I believe the problem to be entirely fixed there. The issues that drove me back to 3.13 were regarding other hardware, not wifi. :-) Are you still interested in older kernels? Unless you have another specific preference, I'll try 3.15-rc2 next. If it works, I can try 3.15-rc1, and if not, 3.15-rc3. A lightly redacted syslog for what appears to be a number of failure events is attached. ** Attachment added: "syslog.1" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315221/+attachment/4165372/+files/syslog.1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1315221 Title: 8086:08b1 (rev 6b) [Dell XPS 13 9333] iwlwifi regularly loses connection/becomes unusable on Intel 7260 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1315221/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
