Working: * Linux 7.0.6-200.fc44.x86_64 Broken: * Linux 7.0.7-200.fc44.x86_64 Firmware is unchanged between both tests: * linux-firmware-20260410-1.fc44.noarch * mt7xxx-firmware-20260410-1.fc44.noarch Symptoms match this report: * Wi-Fi works * bluetoothd starts * rfkill shows hci0, not blocked * bluetoothctl reports: No default controller available dmesg: Bluetooth: hci0: Failed to send wmt func ctrl (-22) Booting back into 7.0.6 immediately restores Bluetooth. A full power cut do= es not fix Bluetooth on 7.0.7. --=20 You may reply to this email to add a comment. You are receiving this mail because: You are the assignee for the bug.=
