Assignee: [email protected]

Regression: NoMy bluetooth mouse stopped working when I moved from the kernel 5.8 to 5.9.
When I tried to pair the mouse without touching it, it didn't work.
But if I keep on moving the mouse while pairing it, it works.
If I shutdown the computer or the mouse, I have to pair it again.

CPU : AMD Ryzen 9 4900HS
Mouse : Logitech M720 Triathlon

--- Comment #1 from Leho Kraav ([email protected]) --- Yes, something is wrong with 5.9 bluetooth stack.
My DELL keyboard and MX Ergo mouse both stop connecting after upgrading from 5.8.
I managed to somehow reconnect them once, but after they disconnect in idle, they fail to reconnect on their own and no amount of bluetooth toggling gets them back.
BT toggling shows "[13543.597906] Bluetooth: hci0: HCI reset during shutdown failed" in demsg.

Yes, something is wrong with 5.9 bluetooth stack.
PS I went straight to 5.9.1.

I downgraded to 5.8.16 and everything seems to be working fine again across my home / work locations.
So this does not seem to be about BleedingTooth patches, but something deeper changed during 5.8 -> 5.9 cycle. Unfortunately I don't have to bandwidth to bisect.

--- Comment #5 from Mat ([email protected]) --- Update with the kernel 5.9.2
No need to move the mouse anymore while pairing.
But I still need to repair the mouse everytime the computer/mouse restart.

--- Comment #6 from Leho Kraav ([email protected]) --- Upgraded to 5.8.16 -> 5.9.6.
Something is definitely not right. Both my mouse and keyboard had to be re-paired in order to get them to work.
After I left machine idling for 1h+, keyboard wouldn't automatically reconnect, had to be re-paired again.
I never had any issues with 5.8 and earlier, for as long as I remember.
Is noone knowledgeable about 5.9 BT stack changes really seeing any suspicious behavior with their devices? Something is clearly off, I'm fairly certain I'm not imagining things here.
