Bug description:
=== SRU Justification ===
[Impact]
Qualcomm WiFi/Bluetooth may disappear after boot.
[Fix]
Disable USB2 LPM at shutdown phase, to prevent it from lingering in LPM
L1. Pull back the device to full power before shutdown imitates the
behavior on Windows.
[Test]
The affected user confimed it fixes the issue.
I can also confirm that
a) The power drain in S5 is much lower,
b) Both WiFi and Bluetooth are always present during reboot stress test.
[Regression Potential]
Low. Only a limited number of USB2 devices that support LPM.
=== Original Bug Report ===
Sometimes, the Wireless Network Card QCA9377 is not recognized on boot. This
caused, on prior versions, a kernel panic at boot. With Bionic, the system
boots but is unable to use wireless network. On dmesg there are messages like:
[ 2.680590] usb 1-7: new full-speed USB device number 7 using xhci_hcd
[ 2.808640] usb 1-7: device descriptor read/64, error -71
[ 3.044337] usb 1-7: device descriptor read/64, error -71
[ 3.280064] usb 1-7: new full-speed USB device number 8 using xhci_hcd
[ 3.408245] usb 1-7: device descriptor read/64, error -71
[ 3.644244] usb 1-7: device descriptor read/64, error -71
[ 3.752193] usb usb1-port7: attempt power cycle
[ 4.404591] usb 1-7: new full-speed USB device number 9 using xhci_hcd
[ 4.404904] usb 1-7: Device not responding to setup address.
[ 4.612478] usb 1-7: Device not responding to setup address.
[ 4.820588] usb 1-7: device not accepting address 9, error -71
[ 4.948591] usb 1-7: new full-speed USB device number 10 using xhci_hcd
[ 4.949109] usb 1-7: Device not responding to setup address.
[ 5.156893] usb 1-7: Device not responding to setup address.
[ 5.364589] usb 1-7: device not accepting address 10, error -71
[ 5.364655] usb usb1-port7: unable to enumerate USB device
And lspci and lsusb don't show the wireless network card. The
alternative is to turn the system off. Reboot don't work and reboot to
Windows 10 also don't. The system must be powered off to restore
functionality. Then, on the next boot, it works properly.
However, after the system is turned off, it may cause the issue again.
This is not 100% consistent, but mostly it cycles between powering off
and powering on the notebook as:
Work -> Don't work -> Work -> Don't work
On Windows 10 this doesn't happen but when happens on Ubuntu, it's
possible to reboot and see the status on Windows 10 too: on Device
Manager it's shown a unidentified USB device at 1-7. Sometimes, on
Windows 10's Network Devices it's shown, instead of the QCA9377, from
four to six different devices with generic names and Bluetooth and/or
Wireless don't work.
When turning Ubuntu off, there are messages that appears a few
instants before the system is turned off:
Mar 18 18:27:26 usuario-Lenovo-ideapad-310-14ISK kernel: [14146.403388]
ath10k_pci 0000:02:00.0: failed to install key for vdev 0 peer

Mar 18 18:27:26 usuario-Lenovo-ideapad-310-14ISK kernel: [14146.403399]
wlp2s0: failed to remove key (0, xx:xx:xx:xx:xx:xx) from hardware (-110)
Generally, only the second message appears (but both are recorded on
kern.log). The MAC adress is the one from the router, not from the
wireless card.
