I'm seeing this very same issue on a new Lenovo T590 running 19.10 with linux-firmware 1.182 and linux-image-generic 5.3.0.10.11. See attached files for more verbose info on the network controller and journalctl logs.
Thanks to the previous comment, I can say that the issue is only seen if the system connects to a 5GHz network. ** Attachment added: "journalctl output" https://bugs.launchpad.net/ubuntu/+bug/1808389/+attachment/5290970/+files/journalctl.out -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1808389 Title: iwlwifi Intel 8265 firmware crashing on lenovo x1 Gen 6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1808389/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
