I'm facing an issue that the BT device is gone after I suspend and resume. Kernel say that device is disconnected and thats it. I tried following options for btusb module enable_autosuspend=0 enable_autosuspend=0 reset=1 Also tried set power/persistent = 0/1 but result is still the same. Only reboot helps in bringing it back. In addition I checked that BT + suspend/resume is working fine under Windows 10. Hardware: Lenovo ThinkBook 15 IIL. BIOS is updated to latest one from Lenovo site DJCN18WW 05/08/2020 The BT device is Bus 003 Device 005: ID 8087:0026 Intel Corp. OS is Ubuntu 18.04, issue happens on distro kernel kernel 5.4 and mainline 5.9 Here is USB dev tree before suspand: $ lsusb -t /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 10000M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M |__ Port 6: Dev 3, If 0, Class=Video, Driver=uvcvideo, 480M |__ Port 6: Dev 3, If 1, Class=Video, Driver=uvcvideo, 480M |__ Port 10: Dev 5, If 0, Class=Wireless, Driver=btusb, 12M |__ Port 10: Dev 5, If 1, Class=Wireless, Driver=btusb, 12M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 10000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/1p, 480M And after resume: $ lsusb -t /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 10000M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/12p, 480M |__ Port 6: Dev 3, If 0, Class=Video, Driver=uvcvideo, 480M |__ Port 6: Dev 3, If 1, Class=Video, Driver=uvcvideo, 480M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 10000M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/1p, 480M # dmesg --follow [ 5577.434207] PM: suspend entry (deep) [ 5577.441904] Filesystems sync: 0.007 seconds [ 5577.469737] Freezing user space processes ...

Confirm error, Lenovo ThinkBook 14 IIL

Confirm error, kernel 5.10.26
An still in kernel 5.17. Who we need to pray to to have some attentions from Intel?
Adding BT mailing list. Maybe someone will have some mercy.
They officially admitted that Intel don't GF about that issue. Official suggested "workarounds" can be found here: https://community.intel.com/t5/Wireless/AX201-Bluetooth-dead-after-sleep-S3-and-resume-continue/m-p/1412902/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufEw3UEFKTFJFU1U0VjI2fDE0MTI5MDJ8U1VCU0NSSVBUSU9OU3xoSw#M43083
Can confirm the same problem on a Thinkbook 14 ILL,tested with Intel AC 8620 and Intel AC 9560. Works without issue while power on but after resuming from suspend BT disappear. BIOS: DJCN30WW (Latest) Tested distributions: RHEL 9.1 (kernel 5.19) Fedora 37 - 38 (kernel 6.2)
Same here with Thinkbook 15 IIL. Bus 003 Device 005: ID 8087:0026 Intel Corp. AX201 Bluetooth Device dead after a suspend and actually disappears from the listing given by lsusb. No way to get it back. Can this please be picked up?
