Subject: Problem: Bluetooth stops connecting to paired devices after commit
 6a98e3836fa207

Hi,

When testing the latest upstream this morning, my bluetooth mouse
stopped working. Further inspection showed that my laptop is failing to
connect, but I didn't see anything relevant in dmesg, the driver seemed
to load firmware and intialize fine.

A bisect turned up commit 6a98e3836fa207 as the first bad one, but
unfortunately there was another problem discovered during the bisect
where my bluetooth radio failed to come up at all.

I am using a 5 year old Lenovo X1 carbon which is using the Intel
Wireless 8265 / 8275 card and the btintel driver.

I can easily reproduce, and would be happy to test patches or help
diagnose if I can. Is this a known issue?

Regards,
Eric
