I've been having the same problem, the workaround I have is to use older firmware.

[the reason is because other bug reports have confirmed the older firmware alone fixes the issue]. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1848921 Title: iwlwifi firmware crashes intel 9260ac [8086:2526] subsystem [8086:0010] To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1848921/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
