https://bugzilla.kernel.org/show_bug.cgi?id=209659 Bug ID: 209659 Summary: Intel USB bluetooth 8087:0026 device is gone after system resume Product: Drivers Version: 2.5 Kernel Version: 5.9.0-050900 Hardware: Intel OS: Linux Tree: Mainline Status: NEW Severity: blocking Priority: P1 Component: Bluetooth Assignee: linux-bluetooth@xxxxxxxxxxxxxxx Reporter: pawelwod@xxxxxxxxx Regression: No 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 ...
