Bug Description
[Steps to Reproduce]
1. Pair some Bluetooth BLE device. Open a terminal and run `dmesg -w` to make sure Bluetooth is receiving advertisement events and repeatedly printing:
Bluetooth: hci0: advertising data len corrected
...
2. Turn off dim display/blank screen on idle in Settings
3. Shorten long idle suspend time to 2 minutes by:
$ gsettings set org.gnome.
sleep-
4. Idle wait for 2 minute and let system suspend.
5. Resume after 20 seconds suspend or so.
[Expected result]
System resumes normally.
[Actual result]
* Screen lighted up, sent to GDM greeter as expected, but UI freeze when pressed ENTER to submit filled account name/password.
* No console switch is possible.
* Kernel alive because rescue magic key is the only way to escape.
* The last line in syslog is:
kernel [...] PM: suspend entry (deep)
* When Bluetooth is rfkilled, this issue is not happening. When Bluetooth has never paired to BLE devices, this issue is no happening, either.
