Sorry for the double send on the original message. I am still hoping to
get some help. I have added additional info below.

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

Updated today. Here's the new uname:
Linux braindead.localdomain
6.9.0-0.rc2.20240405git8cb4a9a82b21.27.fc41.x86_64 #1 SMP

I also noticed a new version of bluez. Here is the RPM package version:
bluez-5.73-3.fc41.x86_64
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)
I did notice that the mouse seems to work in Plasma until a few sec
after I see the background image appears. I suspect that Plasma is
disabling and reenabling the bluetooth where Gnome does not do that.
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

Logs are mostly unchanges when restarting the bluetooth service after a
cold boot with the bluetooth originally working.
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.
I will also say that the bluetooth appears to work throught a
suspend/resume cycle as long as I don't restart the bluetooth service.
Oh, and my laptop is a Dell 9310 if that helps.
Is there any other info I could collect that might be useful?
I'm pretty new to troubleshooting a problem like this and would be happy
to have any advice anyone might want to share.
Thanks,
wt
