I have had no issues anymore since I switched to my self built 1.177~ppa0f22c85 (PPA) - while before they were rather common.
Thanks for accepting that into Bionic-Proposed. I have switched to 1.173.5 from Proposed and unplugged the cables. The install (a downgrade for me as outlined) itself worked fine, I'll reboot now and check on Monday I'll check if any connectivity issues came up over the weekend. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1808389 Title: iwlwifi Intel 8265 firmware crashing on lenovo x1 Gen 6 Status in Ubuntu: Confirmed Status in linux-firmware package in Ubuntu: Fix Committed Status in The Bionic Beaver: Confirmed Status in linux-firmware source package in Bionic: Fix Committed Status in The Cosmic Cuttlefish: Confirmed Status in linux-firmware source package in Cosmic: Fix Committed Bug description: SRU Justification: =============== [Impact] repeated crashes of the Intel 8265 wireless card on a Lenovo X1 Gen6.
