@mapengyu Installed the test kernel. dmesg looks identical to -38. Will report back asap.
I didn't notice that before but both -38 and the test kernel having issues initializing intelbt: ``` [ 23.139943] kernel: usbcore: registered new interface driver btusb [ 23.165732] kernel: Bluetooth: hci0: Found device firmware: intel/ibt-20-1-3.sfi [ 23.165932] kernel: Bluetooth: hci0: Boot Address: 0x24800 [ 23.165936] kernel: Bluetooth: hci0: Firmware Version: 255-255.255 [ 23.167264] kernel: usb 1-3: USB disconnect, device number 2 [ 23.167505] kernel: Bluetooth: hci0: FW download error recovery failed (-19) [ 23.167581] kernel: Bluetooth: hci0: sending frame failed (-19) [ 23.168557] kernel: Bluetooth: hci0: Reading supported features failed (-19) [ 23.168563] kernel: Bluetooth: hci0: Error reading debug features [ 23.168567] kernel: Bluetooth: hci0: HCI LE Coded PHY feature bit is set, but its usage is not supported.

P.S. Despite initial erros, bluetooth works (at least initially) with both -38 and test kernels. ** Attachment added: "dmesg for -36, -38 and test kernels" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2073047/+attachment/5798178/+files/dmesg.tar.xz -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2073047 Title: Regression on Linux 6.8.0-38: Bluetooth adapter (Intel AX200) stops working after a few suspend/resume cycles To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2073047/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
