Description: Ubuntu 23.10 Release: 23.10 -- 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/2036428 Title: Intel AX201 Bluetooth not available with 20230915.gitdfa11466-0ubuntu1 Status in linux-firmware package in Ubuntu: Fix Released Bug description: After upgrading linux-firmware to 20230915.gitdfa11466-0ubuntu1, my Intel AX201 Bluetooth controller is not available post-reboot. The device itself shows up here: $ lsusb | grep -i blue Bus 003 Device 005: ID 8087:0026 Intel Corp. AX201 Bluetooth But running e.g. `dmesg | grep -i bluetooth` returns no matches, and bluetoothctl finds no controllers. Reverting to the 20230323.gitbcdcfbcf-0ubuntu1.6 package restores full functionality. n.b. Possible duplicate of LP:2036348 - I am not in a position to confirm those symptoms yet, but will update later. Running mantic pre-release on amd64: $ lsb_release -rd No LSB modules are available.
