Bug#1133685: Intel AX200 Bluetooth non-functional on 5.10.0-39, regression from 5.10.0-38
Hello and thanks for responding, I am unable to boot into 5.10.0-38 on this system. GRUB appears to be overridden by something at the firmware or bootloader level - grub-set-default, grub-reboot, and manual grub.cfg configuration all fail to change the boot target. Both kernels are installed. I can only provide logs from 5.10.0-39. Attached are the logs for 5.10.0-39. If the logs for 5.10.0-38 are critical I can try entirely reverting back to that build.

Can you please provide boot logs for both 5.10.0-38-amd64 and 5.10.0-39-amd64? Best regards Uwe signature.asc Description: PGP signature
Bug#1133685: Intel AX200 Bluetooth non-functional on 5.10.0-39, regression from 5.10.0-38
Package: linux Version: 5.10.251-1 Severity: important Intel Wi-Fi 6 AX200 Bluetooth stopped functioning after upgrading from kernel 5.10.0-38-amd64 (5.10.249-1) to 5.10.0-39-amd64 (5.10.251-1). WiFi on the same card continues to work normally. Symptoms: - GNOME Bluetooth settings reports "No Bluetooth found" - hciconfig -a and hcitool dev return no devices - /sys/class/bluetooth does not exist at boot - bluetooth.service skips repeatedly due to missing ConditionPathIsDirectory - btintel module is present but does not bind to the device dmesg shows WiFi firmware loads normally but no BT firmware load attempt appears anywhere in the log. On a working system a separate btintel/iwlwifi line loading BT firmware would be expected alongside the wifi firmware load. Hardware: - Intel Wi-Fi 6 AX200 160MHz, PCIe, :01:00.0, REV=0x340 - Firmware: iwlwifi-cc-a0-59.ucode, version 59.601f3a66.0 Kernel versions: - 5.10.0-38-amd64 (5.10.249-1): Bluetooth working prior to upgrade - 5.10.0-39-amd64 (5.10.251-1): Bluetooth broken Regression timing confirmed via /var/log/dpkg.log showing kernel upgradeoccurred April 12 2026.
