This issue is still present on kernel 6.7.1 and firmware 20240115. Opening a new bug for this as directed in this old bug: https://bugzilla.kernel.org/show_bug.cgi?id=215167 $ uname -a Linux andromeda 6.7.1-arch1-1 #1 SMP PREEMPT_DYNAMIC Sun, 21 Jan 2024 22:14:10 +0000 x86_64 GNU/Linux $ lsusb | grep -i bluetooth Bus 001 Device 006: ID 8087:0029 Intel Corp.

This issue is still present in kernel 6.7.2
I'm also experiencing this issue. It started with kernel 6.5. Bluetooth has been broken ever since. The issue was not present in earlier versions of the kernel. ``` $ uname -a Linux 6.5.0-17-generic #17~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Tue Jan 16 14:32:32 UTC 2 x86_64 x86_64 x86_64 GNU/Linux ``` ``` $ lsusb | grep -i bluetooth Bus 001 Device 004: ID 8087:0032 Intel Corp.

This issue is still present in kernel 6.7.3
I discovered that Bluetooth starts working again after a cold boot (shutdown, disconnect power for 30 seconds, then boot normally).
Bluetooth still does not work with 6.7.4, however the logs have changed from the error that was shown before: $ journalctl -b | grep -E -i bluetooth Feb 11 14:27:14 andromeda kernel: Bluetooth: Core ver 2.22 Feb 11 14:27:14 andromeda kernel: NET: Registered PF_BLUETOOTH protocol family Feb 11 14:27:14 andromeda kernel: Bluetooth: HCI device and connection manager initialized Feb 11 14:27:14 andromeda kernel: Bluetooth: HCI socket layer initialized Feb 11 14:27:14 andromeda kernel: Bluetooth: L2CAP socket layer initialized Feb 11 14:27:14 andromeda kernel: Bluetooth: SCO socket layer initialized Feb 11 14:27:14 andromeda kernel: Bluetooth: hci0: Found device firmware: intel/ibt-20-1-3.sfi Feb 11 14:27:14 andromeda kernel: Bluetooth: hci0: Boot Address: 0x24800 Feb 11 14:27:14 andromeda kernel: Bluetooth: hci0: Firmware Version: 255-255.255 Feb 11 14:27:15 andromeda systemd[1]: Reached target Bluetooth Support.

I have the same issue as Nickolas, turning off the computer does not help. The device is also the same: Intel AX200 8087:0029.

I wonder, how did you enable these extra debug messages in journalctl? For example, in mine it doesn't say anything about which firmware files it tries to load. I was trying to identify what it loads to replace them with some older versions and see if I can make it work that way. I also want to confirm again that the issue is still present in kernel 6.8.1 with the latest firmware update: 20240312
Had the same issue. Somehow, after a long power-off and turning on again, Bluetooth managed to show up and the message was gone. Using an AX200 as well. Currently using kernel 6.8.2

This is very weird behavior. Sadly, its short lived. Mine stopped working again after the first resume from suspend that occurred after the cold boot.

Yes, same here, after normal reboot or shutdown (assuming it happens, because it also hangs on shutdown/reboot now), it **only** works after PSU power cycle

Turn of, waited few seconds and then power on again. Have a Intel AX200 chip and Linux archlinux 6.8.2-arch2-1 #1 SMP PREEMPT_DYNAMIC Thu, 28 Mar 2024 17:06:35 +0000 x86_64 GNU/Linux
I can also confirm the issue. I tried using latest kernel 6.8.2.arch2-1 on arch linux, and also LTS version 6.6.23-1 and on both I see same behavior. $ lsusb | grep -i bluetooth Bus 001 Device 004: ID 8087:0029 Intel Corp. AX200 Bluetooth The behavior is exactly the same as other described.

I get a null pointer deref on boot and bluetooth is broken: [ 2.317366] BUG: kernel NULL pointer dereference, address: 0000000000000070 [ 2.317699] #PF: supervisor read access in kernel mode [ 2.317993] #PF: error_code(0x0000) - not-present page [ 2.318280] PGD 0 P4D 0 [ 2.318283] Oops: 0000 [#1] PREEMPT SMP NOPTI [ 2.318842] CPU: 3 PID: 185 Comm: kworker/u33:0 Not tainted 6.8.3-gentoo-dist #1 [ 2.318844] Hardware name: AZW SER/SER, BIOS SER7PRO_P5C8V30 09/15/2023 [ 2.318845] Workqueue: hci0 hci_alloc_dev_priv [bluetooth] [ 2.319426] RIP: 0010:btintel_configure_setup+0x245/0x970 [btintel] [ 2.320365] Code: 85 ff 75 a1 f0 41 80 8e 51 06 00 00 02 f0 41 80 8e 51 06 00 00 04 f0 41 80 8e 51 06 00 00 08 49 c7 86 38 17 00 00 b0 63 66 c1 <83> 7b 70 0a 75 7b 48 8b 83 d0 00 00 00 80 78 01 37 75 6e 0f 1f 44 [ 2.320691] RSP: 0018:ffffa215005cfd48 EFLAGS: 00010202 [ 2.321452] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000080200006 [ 2.321760] RDX: 0000000080200007 RSI: ffffd3238404d700 RDI: 0000000000000000 [ 2.322437] RBP: ffff91a940ccc6c8 R08: 0000000080200007 R09: 0000000080200006 [ 2.322438] R10: 0000000000000001 R11: 0000000000000000 R12: ffff91a940ccc6d0 [ 2.322439] R13: ffff91a947f50c00 R14: ffff91a940ccc000 R15: ffff91a940ccca88 [ 2.322441] FS: 0000000000000000(0000) GS:ffff91af820c0000(0000) knlGS:0000000000000000 [ 2.323737] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 2.323739] CR2: 0000000000000070 CR3: 000000010dfa2000 CR4: 0000000000f50ef0 [ 2.323740] PKRU: 55555554 [ 2.323740] Call Trace: [ 2.323743] <TASK> [ 2.326248] ? __die_body+0x68/0xb0 [ 2.326253] ? page_fault_oops+0x3a3/0x400 [ 2.326256] ? exc_page_fault+0x60/0xf0 [ 2.326265] ? asm_exc_page_fault+0x26/0x30 [ 2.326269] ? btintel_configure_setup+0x245/0x970 [btintel] [ 2.328091] ? btintel_configure_setup+0x16c/0x970 [btintel] [ 2.328093] ? __ia32_compat_sys_sysinfo+0x230/0x270 [ 2.329006] hci_dev_open_sync+0x166/0x1610 [bluetooth] [ 2.329013] ? srso_alias_return_thunk+0x5/0xfbef5 [ 2.329015] ? srso_alias_return_thunk+0x5/0xfbef5 [ 2.329016] ? srso_alias_return_thunk+0x5/0xfbef5 [ 2.329018] hci_alloc_dev_priv+0x164e/0x1bc0 [bluetooth] [ 2.329023] process_scheduled_works+0x24b/0x450 [ 2.329026] worker_thread+0x2c3/0x420 [ 2.329028] ? __pfx_worker_thread+0x10/0x10 [ 2.329030] kthread+0xe8/0x110 [ 2.329032] ? __pfx_kthread+0x10/0x10 [ 2.329033] ret_from_fork+0x37/0x50 [ 2.329036] ? __pfx_kthread+0x10/0x10 [ 2.329038] ret_from_fork_asm+0x1b/0x30 [ 2.329043] </TASK> [ 2.329043] Modules linked in: amdxcp(+) ac97_bus(+) iwlwifi(+) snd_hda_codec(+) btusb snd_pcm_dmaengine gpu_sched vfat btbcm snd_pci_ps drm_suballoc_helper btintel i2c_algo_bit fat snd_rpl_pci_acp6x kvm(+) drm_ttm_helper snd_hda_core snd_acp_pci btrtl ttm snd_acp_legacy_common btmtk snd_pci_acp6x irqbypass drm_exec snd_hwdep snd_pci_acp5x snd_pcm drm_display_helper bluetooth snd_rn_pci_acp3x wmi_bmof cfg80211 snd_timer snd_acp_config rapl cec snd_soc_acpi snd pcspkr drm_buddy soundcore i2c_piix4 k10temp snd_pci_acp3x rfkill amd_pmc fuse loop nfnetlink crct10dif_pclmul crc32_pclmul crc32c_intel nvme polyval_clmulni polyval_generic ghash_clmulni_intel thunderbolt sha512_ssse3 sha256_ssse3 sha1_ssse3 nvme_core amd_sfh ccp sp5100_tco r8169 nvme_auth realtek video wmi i2c_hid_acpi i2c_hid serio_raw [ 2.329083] CR2: 0000000000000070 [ 2.329085] ---[ end trace 0000000000000000 ]--- [ 2.329087] RIP: 0010:btintel_configure_setup+0x245/0x970 [btintel] [ 2.329089] Code: 85 ff 75 a1 f0 41 80 8e 51 06 00 00 02 f0 41 80 8e 51 06 00 00 04 f0 41 80 8e 51 06 00 00 08 49 c7 86 38 17 00 00 b0 63 66 c1 <83> 7b 70 0a 75 7b 48 8b 83 d0 00 00 00 80 78 01 37 75 6e 0f 1f 44 [ 2.329090] RSP: 0018:ffffa215005cfd48 EFLAGS: 00010202 [ 2.329091] RAX: 0000000000000000 RBX: 0000000000000000 RCX: 0000000080200006 [ 2.329092] RDX: 0000000080200007 RSI: ffffd3238404d700 RDI: 0000000000000000 [ 2.329093] RBP: ffff91a940ccc6c8 R08: 0000000080200007 R09: 0000000080200006 [ 2.329093] R10: 0000000000000001 R11: 0000000000000000 R12: ffff91a940ccc6d0 [ 2.329094] R13: ffff91a947f50c00 R14: ffff91a940ccc000 R15: ffff91a940ccca88 [ 2.329095] FS: 0000000000000000(0000) GS:ffff91af820c0000(0000) knlGS:0000000000000000 [ 2.329096] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 2.329096] CR2: 0000000000000070 CR3: 000000010dfa2000 CR4: 0000000000f50ef0 [ 2.329097] PKRU: 55555554 [ 2.329098] note: kworker/u33:0[185] exited with irqs disabled
The issue has been fixed for me after upgrading to kernel 6.8.4-arch1-1 on Arch-linux.
(In reply to Jugoslav Gacas from comment #18) > The issue has been fixed for me after upgrading to kernel 6.8.4-arch1-1 on > Arch-linux. Can confirm. Upgraded kernel to 6.8.4-arch1-1, removed btusb from the module loading blacklist, powered-off the PC and powering it on again, bluetooth was working. Tried several things such as rebooting, rebooting on my Windows drive, rebooting to Archlinux again, powering-off: no power-off hanging, and bluetooth was working immediately after each start-up, without having to deal with modprobe anyhow.
I am on kernel 6.8.4 and using firmware 20242312, but Bluetooth is still not working for me: $ uname -a Linux andromeda 6.8.4-arch1-1 #1 SMP PREEMPT_DYNAMIC Fri, 05 Apr 2024 00:14:23 +0000 x86_64 GNU/Linux $ journalctl -b | grep -E -i bluetooth Apr 09 07:01:20 andromeda kernel: Bluetooth: Core ver 2.22 Apr 09 07:01:20 andromeda kernel: NET: Registered PF_BLUETOOTH protocol family Apr 09 07:01:20 andromeda kernel: Bluetooth: HCI device and connection manager initialized Apr 09 07:01:20 andromeda kernel: Bluetooth: HCI socket layer initialized Apr 09 07:01:20 andromeda kernel: Bluetooth: L2CAP socket layer initialized Apr 09 07:01:20 andromeda kernel: Bluetooth: SCO socket layer initialized Apr 09 07:01:21 andromeda systemd[1]: Reached target Bluetooth Support.

Sorry, a typo in my last comment, firmware 20240312 is what I meant.
(In reply to Nickolas Gupton from comment #21) > Sorry, a typo in my last comment, firmware 20240312 is what I meant. make sure you do full "power on - power off - power on" cycle **with fixed kernel**, it's known that warm boot or older kernel somewhere in this cycle prevent Bluetooth to recover.
Yeah, I turn my PC off every night. Have turned it on from a cold power off every morning for the last year or so this hasn't been working. That doesn't help at all, the only thing that works to get Bluetooth working after boot is running the script I showed in a previous comment.
Does this have any relation to the message I am seeing in the journal logs after warm boot? Namely this: Bluetooth: hci0: command 0xfc00 tx timeout I can confirm that I still get this message on a mainline kernel build. I have started a thread on linux-bluetooth with the subject "QCA6390 bluetooth doesn't work after warm boot or disable/reenable" if that helps.
