Public bug reported:
When system has been paired with BLE devices, bluetooth firmware may
fail to suspend, or even hangs the whole system that it can only be
rebooted with SysRq keys.
[Reproduce steps]:
1. pair with BLE devices. They doesn't have to stay connected/powered on
during the test.
2. make sure Bluetooth is now receiving LE ADV broadcats, which should
leave messages in dmesg like:
Bluetooth: hci0: advertising data len corrected
3. suspend the system a few times. With 5.0.0-1025-oem-osp1 kernel,
symptoms would usually appear in <= 5 times.
[Results]
1. one may observed following errors in between the suspend messages:
PM: pci_pm_suspend(): hcd_pci_suspend+0x0/0x30 returns -16
PM: dpm_run_callback(): pci_pm_suspend+0x0/0x150 returns -16
PM: Device 0000:00:14.0 failed to suspend async: error -16
PM: Some devices failed to suspend, or early wake event detected
where 0000:00:14.0 is the xHCI Usb hub.
2. with or without above error messages appear first, system may hang
and leave only "PM: suspend entry (deep)" in the syslog.
[Notes]
* kernels newer than v5.2.1, inclusive of latest v5.4-rc5, still have
those PM suspend errors, but they doesn't seem to cause system block.
Instead, they may resume immediately.
* this was found on one platform with Intel Dual Band Wireless AC 9462
