Output of lsusb (wifi/bluetooth chip is connected via usb on T490)
I'm experiencing the same problem. I'm also unable to reconnect to bluetooth
devices after the pairing and the initial connect succeeded.

I have the same issue
Device was discovered and connected fine the first time, then it was
disconnected immediately.
Every time I try to connect it again, it disconnects.

This bug occurs after a software suspend/resume cycle. It's valid and it needs
to be fixed. Some logic in the driver doesn't handle suspend properly.

Of course you are seeing that error if you use 5.4 and the fix landed in 5.6
with no backports?
If any the true shame is that nobody has yet addressed the same problem with
"force_bredr_smp"

Guess we'll have to wait 5.11 if any kind of backporting is unthinkable.

Hi all. I don't see why only 5.11 fixes this. As for me I see such an issue
after BT was off and there was the sleep of laptop.
