[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 [8086:02f0] subsystem id [8086:42a4], linux-firmware 1.173.11 with intel/ibt-19-0-0.sfi REL0282. However, it's not reproducible on another platform with same hw/fw/kernel configuration. kernel: [ 78.136285] PM: suspend entry (deep) kernel: [ 78.139836] Filesystems sync: 0.003 seconds kernel: [ 78.140461] Freezing user space processes ...
