Looks like a duplicate of bug 1830192, but it's not. TX A-MSDU was not enabled previously on 4.15.
And, no, it's not a duplicate of https://bugzilla.kernel.org/show_bug.cgi?id=204167, either. This one shows no sign of that at all. So far I cannot reproduce this with a 8260 chip locally against reported 4.15.0-101-generic connecting to an either 5G or 2.4G WLAN, with or without backport-iwlwifi-dkms installed, even under some stress enable/disable tests. Could you try install backport-iwlwifi-dkms on your system? Or do you have some more deterministic way to reproduce it? $ sudo apt update && sudo apt install backport-iwlwifi-dkms ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1880426 Title: Intel Wireless-AC 8260 [8086:24f3] Subsystem [8086:1010] - iwlwifi Microcode SW error detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1880426/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
