-- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1885266 Title: iwlwifi causes random UI freezes Status in linux package in Ubuntu: Confirmed Bug description: The GUI randomly freezes around every 10-15 minutes. This last for about 15-20 seconds before it gets back to normal. It started a few weeks ago. I can see entries in dmesg when this happens that make me suspect that it is caused by iwlwifi and/or a related driver of the Intel Wireless-AC 9260.
