Hey there ath11k/bluetooth folks,
I am having a pretty major problem with QCA6930 for some time (maybe a
year or two). I have this bluetooth device:
72:00.0 Unassigned class [ff00]: Qualcomm Technologies, Inc QCA6390
Wireless Network Adapter
This device appears to be driven by the ath11k module and others. I hope
I am pinging the right lists.
I am using Fedora Rawhide. Fully updated yesterday. My uname reports this:
Linux braindead.localdomain
6.9.0-0.rc2.20240402git026e680b0a08.24.fc41.x86_64 #1 SMP
PREEMPT_DYNAMIC Tue Apr 2 17:51:18 UTC 2024 x86_64 GNU/Linux
My main bluetooth device is a Logitech MX 3 Mac mouse that uses
bluetooth. When bluetooth fails, so does the mouse. I have power cycle
my laptop when that happens. I'd love to help find a fix for this.
The problem is that I cannot disable and re-enable the bluetooth on my
system. Bluetooth also doesn't work after a warm boot. I have to power
cycle my laptop to recover bluetooth funcitonality. I have tried the
following:
* logging into KDE Plasma (bluetooth stops working)
* logging into GNOME (works on cold boot, fails on warm boot)
After logging into GNOME during a cold boot, I have also done "systemctl
restart bluetooth.service". I get these journal logs during the stop;

There's a bunch of errors in those logs starting with these two
seemingly important lines:
Apr 04 10:15:06 braindead.localdomain kernel: Bluetooth: hci0: QCA
Failed to send TLV segment (-110)
Apr 04 10:15:06 braindead.localdomain kernel: Bluetooth: hci0: QCA
Failed to download patch (-110)
FWIW, I get similar logs after logging into KDE Plasma. I also get
similar logs after a warm boot.
This appears to be some kind of bug in the initialization of the
hardware. Is there any additional information I can provide to help
troubleshoot this problem.
