Reverting back to an older kernel works. I could bisect *if this issue is not known*, but it may take a while... If you are already suspicious of a commit lemme know, and I can try to revert. Otherwise if there's a firmware version that is supposed to work I'm happy to try that. Device: Intel dual band wireless AC 7260, REV=0x144 Firmware version: 16.242414.0 (linux-firmware upstream) I also tried: Firmware version: 17.246894.0 op_mode iwlmvm (latest on iwlwifi/linux-firmware.git) I run into the same issue with this version as well though.
