Kernel version: 4.4.0-98-generic
Kernel snap: caracalla-kernel version:4.4.0-98.121-1 revision:58
BIOS version: 01.00.05 (Also tested with 01.00.03)
Tested SKU: T, Media, GPA

The reproduce steps:
1. Enable Wowlan and Wol in BIOS
2. Boot up Ubuntu core
3. Connect to Wifi AP
    $ nmcli d wifi connect <my ssid> password <my password>
4. Enable wowlan
    $ sudo iw phy phy0 wowlan enable magic-packet
5. Enter suspend or hibernate
    $ sudo systemctl suspend
    $ sudo systemctl hibernate
6. Send wake signal from another machine
    # wakeonlan <Wifi MAC>
    # sudo etherwake <Wifi MAC>
7. If system not waked, try to wol or other wake source
    # wakeonlan <Ethernet MAC>
8. After resume, check the wifi/BT function, but not functioning.
    $ nmcli dev
        eth0 ethernet connected Wired connection 1
        wlan0 wifi disconnected --
        eth1 ethernet unavailable --
        cdc-wdm0 gsm unavailable --
        lo loopback unmanaged --
    $ nmcli dev wifi rescan
    $ nmcli dev wfii list
    No wifi APs found

    $ sudo bluetoothctl
        [NEW] Controller 00:23:A7:EA:65:64 0225399 [default]
        [bluetooth]# power on
        Failed to set power on: org.bluez.Error.Failed

The not functioning issue can be fixed by reload driver.
Also hibernate wakeup fails, and wake by other wake source. The Wifi/BT still functioning which could be the FW is reloaded by driver.

This bug is awaiting verification that the 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-xenial' to 'verification-done-xenial'. If the problem still exists, change the tag 'verification-needed-xenial' to 'verification-failed-xenial'.

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 for documentation how to enable and use -proposed. Thank you!
