Bug description:
[SRU Justification]
[Impact]
WCN6856 BT keep in OFF state after coldboot system.
[Fix]
Mainline commit 599ece4f8f07 ("Bluetooth: btusb: Improve stability for
QCA devices") added a 100ms delay for the underlying hw to apply
downloaded firmware.
[Test Case]
This can be reproduced and therefore verified by checkbox poweroff
stress test:
$ checkbox-cli run com.canonical.certification::stress/poweroff
[Where problems could occur]
Unlikely to have side effect so far except slowing down boot process for
a tiny moment.
[Other Info]
While this is only in the v5.18 merge window, all the kernels in use are
affected and nominated here.
== original bug report ==
[Reproduce Steps]
1.Insert WCN6856 card to SUT.
2.Press power button to power on SUT.
3.Clean install Ubuntu 20.04.
4.Check BT function after installation is complete.
5.Coldboot system and check the BT function.
6.Repeat step5, Issue occur.
7.Only found with CB, can't reproduce on WB.
[Results]
Expected Result
BT function work normally.
Actual Result
BT has no function. Can't turn ON BT function. Need CB to recover BT
function.
"WB" and "swicth tab" cannot restore the BT function.
[Others]
Wifi function work normally.

[Kernel-packages] [Bug 1967067] Re: WCN6856 BT keep in OFF state after coldboot system
This bug is awaiting verification that the linux/5.15.0-28.29 kernel in
-proposed solves the problem. Please test the kernel and update this bug
with the results. If the problem is solved, change the tag
'verification-needed-jammy' to 'verification-done-jammy'. If the problem
still exists, change the tag 'verification-needed-jammy' to
'verification-failed-jammy'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

QCA devices") added a 100ms delay for the underlying hw to apply
downloaded firmware.
[Test Case]
This can be reproduced and therefore verified by checkbox poweroff
stress test:
$ checkbox-cli run com.canonical.certification::stress/poweroff
[Where problems could occur]
Unlikely to have side effect so far except slowing down boot process for
a tiny moment.
[Other Info]
While this is only in the v5.18 merge window, all the kernels in use are
affected and nominated here.
== original bug report ==
[Reproduce Steps]
1.Insert WCN6856 card to SUT.
2.Press power button to power on SUT.
3.Clean install Ubuntu 20.04.
4.Check BT function after installation is complete.
5.Coldboot system and check the BT function.
6.Repeat step5, Issue occur.
7.Only found with CB, can't reproduce on WB.
[Results]
Expected Result
BT function work normally.
Actual Result
BT has no function. Can't turn ON BT function. Need CB to recover BT
function.
"WB" and "swicth tab" cannot restore the BT function.
[Others]
Wifi function work normally.

[Kernel-packages] [Bug 1967067] Re: WCN6856 BT keep in OFF state after coldboot system
With linux-oem-5.14/5.14.0-1033.36, this issue is not reproducible
within 20 cold reboots.
A script is used to run rtcwake to cold boot 20 times and attach
`bluetoothctl scan on` result to a log file. If the bluetooth device
cannot be probed, the scan should output "No default controller
available". There was no such error when using 5.14.0-1033.36 kernel.

[Kernel-packages] [Bug 1967067] Re: WCN6856 BT keep in OFF state after coldboot system
This bug is awaiting verification that the linux-oem-5.14/5.14.0-1033.36
kernel in -proposed solves the problem. Please test the kernel and
update this bug with the results. If the problem is solved, change the
tag 'verification-needed-focal' to 'verification-done-focal'. If the
problem still exists, change the tag 'verification-needed-focal' to
'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!
